My tuning experience: Why TGV and EGR deletes are a must

[rufus819]

It will be interesting to see what my driving will be like this season, since we haven't had a true warm day yet this year I have nothing to compare it to from last summer.

I also don't really drive my car that hard on a day to day right now. Maybe it's because I'm growing up

Does anyone know how well these mods will do with passing smog inspections? Will the ecu check from the smog station see the changed codes that the tuner put in? I dont think they are so obvious that they would fail the visual inspection. Any opinions on that?

[rufus819]

In my state (NJ), inspection is once every 5 years and it's become a joke. They do a gas cap test and if your car isn't throwing any generic codes, you pass. If you're unlucky they'll do a visual inspection too.

Same thing im doing in two weeks. Also came from a stage 2 08 spec b tuned by mikey haha. After speaking with him, makes sense to go with TGV/EGR deletes vs a j pipe - similar gains but big price difference and time for install! Wasnt expecting this coming from an 08 spec b and an '11 STI where downpipe is essentially the first mod that comes to mind as being worthwhile.

Im on the fence on whether or not to add an EBCS. Can you post a video of the sound?
$300 for an intake for noise that id probably get sick of shortly after install is crazy. $150 on an EBCS for something a little more subtle might be worthwhile, while keeping boost more consistent.

EBCS is definitely worthwhile and if you're being tuned at EFI, Pete will probably tell you to do one anyways. You can get one from subispeed for $120 ish. I don't have any sounds of the EBCS itself, I can only really hear it inside the car when the turbo energizes and you hear a flutter (which is normal). Here's a video of my car on the dyno though:

For the extra $50, do the EGR deletes. It's not a huge power gain but you'll reduce carbon build up. I like the MAP stage 2 package, it gives a big power boost right out of the box, but I wanted to go my own path and yes get a separate tune for 93 if you can. When I used to own my Spec B I was initially tuned for 91 by Crawford Performance in 2011 (I was stationed in San Diego) and when I came home east I was retuned for 93 by EFI Logics and there was about a 10/10 difference between the 2.

I was checking out some YouTube vids last night of EGRD stuff, and seeing the amount of carbon in the EGR, cars new and old, is enough to make me do it. Plus the lower op temps like folks are mentioning. From the little that I've seen. the difference between 91 and 93 is pretty noticeable

Also, talking with Ian from MAP, I asked if it might be beneficial for them protuning my car, for me to have an EBCS. Interestingly, he said from the testing they've done, the MAP tuner has been able to produce results equal to or better than an aftermarket EBCS using just the stock setup. I dunno what kind of wizardry they're doing down there, but I'm excited to see what they eventually do to my car.

I made a little vlog about my car today. It's nothing new from what I've said here but you can see other things about my car done too. I'll make more in the coming months of the development of the car, meets and other things going on in the car community!

There's also the Company 23 "anti-surge" EBCS out that eliminates the flutter. Its more expensive, but worth it? Can't find any reviews of it.

I have a GS ebcs, don't know if I will install it as I plan to use MAP Stage 2 tune included w the dp and intake I bought. They also don't have a supported ebcs tune so I figure may as well test their Stage 2 out first since the dyno #'s are very good for 91/93 octane. To date their Stage 1 tune has been excellent for me.

Following using their stage 2 for a while I will have to source out a solid etuner, probably gonna choose TP to tune my additional parts, TGV, EGR and PRL charge pipe and the ebcs.

The GS was the one I was eyeing. Same here- I was using Cobb's stage 1 93 tune for the Mishi intake, then switched to MAP's Stage 1 93, and the difference is night and day. I figure I'll also ask for their Stage 2 tune after I throw on their catted DP, and then install my TGV and EGR deletes right before I bring my car down to them for protuning. I still haven't figured how I'm going to do a short term tune accounting for the DP, TGV & EGR deletes just so I can drive the 30 miles to have them tune it.

[rufus819]

I would still get a custom tune to your car. The MAPerformance package looks like a great deal and all, but from a lot of things I've gathered with this engine is every one of them needs their own custom tune to your mods, driving style etc. On the EJ motor you could throw another persons map on and it would run just fine but these cars all seem to need a custom tune per vehicle. Either way I think the EBCS is a cheap enough upgrade that doing it is a no brainer and it keeps your low end torque in check and your boost consistent

[DoctorPopcorn]

Right, I'll be getting it protuned by MAPerformance once everything is on, and I'll throw on the TGVDs and EGRD right before I bring it to them, and maybe a nice clean oil change the week before wouldn't be a bad idea.

I plan on using their stage 2 just in the meantime, after I install the downpipe (so I'll just have my intake and DP on the car). I won't be turning the key on the car without a specific tune for both of the deletes

[rufus819]

A fresh oil change before you get on the dyno is a good idea, if you're within 1000 miles since your last one you'll be good, if not change it. My tuning session at EFI was 2 hours long and Mikey did over 30 pulls so I'm glad I did a bunch of my own prep work the day before.

[DoctorPopcorn]

Indeed. A fresh oil change, coupled with Perrin and Torque Solutions motor, transmission, and pitch stop mounts will give me more peace of mind

[Gro Harlem]

I should prolly get a pro-tune for my Verticooler+charge pipe / EGR/TGV delete / Turboback setup I'm running. Using an e-tune currently but doesn't feel as fast as I'd expect it to with all htese other Dyno sheets I'm seeing pushing over 300whp/320wtq makes me jelly.

[Nuked]

As soon as Cobb enables the Stratified/Homogeneous switch in ATR I plan to do these. I am interested in what kind of part throttle drive ability and mileage increases the mod can achieve.

I have the grimspeed ebcs and I can tell you the flutter is almost on the verge of loud. I'd post a video from in car but I can't post pics/videos yet!

[rufus819]

So far since I've been tuned and I've filled up twice and averaging 25 mpg mixed driving. I haven't really had many opportunities to really get on it because it seems like in North Jersey all I ever do is sit in traffic or congested roadways

[bindsti]

Thoughts on doing this with stock catback? Not really looking to make gains; just improve the way the car runs. Not looking to spend ~$1k on a noise maker.

[Gro Harlem]

installed a mishi CAI w/box and grimmspeed EBCS at the same time on my car and i personally like the sound. Its only louder when you give it throttle. On the highway you hear minor whooshes but nothing that is louder than the exhaust or road noise.

Everyone who rides in my car asks what BOV i have since the stock BPV is much more audible. My tuner hates tuning for intakes and told me stock is the way to go for his sake due to irregularities that the aftermarket intakes all seem to introduce into the fueling.

Follow Seeeya's guide on how to modify your stock CBE and remove whatever restrictions are in the muffler. That was the main reason I upgraded to the Cobb, I wanted less restriction/didn't have the time to do what he did. You won't notice a HUGE difference in power from a stock vs. aftermarket catback, maybe a few hp because you'll have less back pressure.

Man you're killing me. I just finished an etune for my tbe and intake. Now I need to do the erg/tgv delete after seeing those numbers I'm assuming I'll be close to 300hp. Damn it, I told myself I'll hold off for a bit. This just reeled me right back in. Nice write up

This is the addiction I have been faced with after transitioning from a '98 Oldsmobile to a '16 WRX.

Leave pitch stop stock, do not mess with it until Perrin releases their fix to the issue or what they believe can aid their current psw, just do your tranny mount and motor mounts if you are able, those are a pita
