Default TGV deletes, EGR delete as well?

Question .... thinking about purchasing stage 1 from BRENtuning - AP, etune, TGV deletes, and Grimspeed ECBS,

I've done some research on the TGV/EGR deletes, and the general consensus is leave both alone, or delete both. Not one or the other. I'm assuming when you do the TGV delete, you are at least unplugging the EGR as well? And then the etune should help with calibrating the air flow/fuel with the deletes?

also plan on adding CBE, if that matters. I guess my question is, do I have to at least unplug the EGR when doing the TGV, or will I be ok just leaving ERG as is. I plan on doing E-tune right after TGV.

The general consensus was that the two work together so if you delete one, you need to delete/deactivate the other. I deleted both, no issues.

Been seeing people who deleted one but not the other had weird issues.

Bren doesn't tune for EGR deletes/removals for emission compliance reasons. If you want Bren to tune your car then EGR deletes/block offs aren't a viable option.

Bren is an excellent tuner, hes tuned hundreds of these cars with only TGVD but not EGRD. If he says it's fine listen to him.

So if I do TGV deletes, and leave EGR as is, the e-tune should clear up any issues with not taking out one or the other.

There are other tuners that do e-tunes for EGR/TGV deletes. I just finished getting it done for EGR/TGV, 3-port EBCS and J-pipe.

The base map he sent for those mods barely needed any tweaking (only 3 other minor revisions based on my logs in a methodical and stepped approach).

I'd say do them both. The EGR delete kit was kind of a pain in the azz to do in the driveway, but in the overall sense of modding, it wasn't that bad. Took me a little longer than the 30 minutes advertised (maybe an hour).

I understand very little about TGV and EGR deletes, however I figured I would share my story to hopefully prevent someone else from repeating my idiotic costly mistake.

A couple months back I had installed on my 2017 wrx the following; grimmspeed catted J pipe, grimmspeed ebcs, and an invidia N1 cat back. Obviously had a dyno tune done as well. Like I said above, I know very little about TGV and EGR deletes so I skipped those things and went about my business.

Well the car was fantastic and making great power until one day I tried to send it in 2nd gear and realized I had a massive boost leak. fml.

Come to find out that my EGR was stuck in the open position causing my boost to just leak right out.

Fast forward to yesterday, I had them install the TGV and EGR deletes and obviously I also needed another tune which was $650. I could have saved myself a lot of money if I would have just done the damn TGV and EGR deletes in the first place.

Moral of the story, don't be an idiot like me. Just do the damn TGV and EGR deletes, save yourself the headache and money.

One case of the EGR failing when it was never touched is hardly a reason to assume that will happen to every car.

Majority of cars on here have both TGV/EGR intact and do fine.

Removing emissions equipment is not practical for everyone, and TGVD/EGRD have definitely caused people problems on here.

You said it yourself, you understand very little about what they do.

That sounds like either there was something wrong with your EGR valve controller or your tuner accidentally removed the EGR functionality somehow.

Partial throttle (15-25% as read on the center display) between ~1500 to ~2700 rpms. Sometimes I had to pay attention to feel it, sometimes it would get my attention. Either way, anything more than 25% throttle and I havenít gotten a hiccup since. Bren recommended I just unplug my egr system but I wasnít comfortable keeping it in place unplugged. Especially since I just moved to a state where emissions testing takes place every year. I just drive around it.

The better question is what crook is charging you 650 for a freakiní retune?

I paid almost half that, from a top tuner. And retunes are at a discount

Initial tune, okay.

But to have the same tuner change like 4 tables in the same freakin' map? Give me a break.

I was planning to go with one tuner, but when I saw that they raised their prices twice in a few weeks (simple overload of work I was told and that prices were going to be raised until an equilibrium was met), I went with someone else. $300 for their e-tune and no regrets.

The other group is repeatedly praised for their work, so my decision was not based on their performance. It was simply a financial decision for me.

phat botti is 500 for etune
bren is 350 - etune
tourqed is still 200. e tune

It is expensive, but apparently it's worth it. But if your paying 500 for etune, might as well go pro tune no?

Clark Turner Tuning e-tune = $300.

Bren is highly reputable and does great work, but won't e-tune TGV/EGR deletes.

He will tune TGVs, he wonít tune EGR. At least as of a few months ago when I had my tune changed.

I think you're right. He sells his FA20DIT stage 1 kit with tgvd so i'm sure he tunes for them.

That was the whole point of the thread. I was thinking about buying stage 1, just didn't know if I had to remove the EGR or unplug etc.
