Doesn't look like that from what I'm looking at.
I see an increase of 25ft lbs tq

FAST - can you elaborate on the boost issues you were having with the turbo and/or setup during the tuning? what steps are you taking to remedy?

The boost wasn't consistent up top above 23 psi They recommended to upgrade the waste gate but they didn't know I had the high boost actuator on it already and preloaded the recommended 8mm. We have decided to leave alone for now but I'm going to look into some other options. I know there has been a few setups on here for boost control. We may do a retune this summer and see what we can come up with.

Nonetheless this car feels great!!

That recommended preload is nothing but a good starting point. You can go a max of 10 if needed.

I haven't run over 15 psi on mine yet but I haven't tried yet so I hope I don't run into issues when I go to crank up the boost. Right now I make 15 psi with 3mm of preload and 40% WGDC at redline. Was boost not repeatable or was it not holding to redline?

I know it was but unfortunately it was too late because it was off the dyno before they asked me about it. There wasn't any of these issues the week prior

You have to make sure you clock the turbo so there is no deflection of the WG arm and that it moves freely. Mine is about 8 degrees from vertical for the WG to line up perfectly.

Wastegate and clocking is completely perfect

I will enjoy this setup for a while then possibly look into the e85 or math route to really take advantage of this turbo. Big thanks to Fast of West Chester for all their time and blood spilt! Hopefully this thread can help others with this setup.

What kind of IDCs are you looking at? Coop expressed to me that you guys had to beef up the pump to make sure you could get there, and I'm wondering what you ended up with
Personally, I wouldn't want it getting that close to 12 if not over 12:1 AFR from 55-6200RPM. What was your target AFR?

OK we must be looking at 2 different charts cause at 4600-4700 your peak torque is at 493 and by 5100-5200 its around 420-430? Any reason for that?

In the future yes. I just paid off all my bills for this build so will enjoy saving money for atleast a year before revisiting any more modifications. The entire process became a domino effect so I am glad I made the choice of not going with the head/cam option from the start.

So I will enjoy as is now and hope to indulge in the future.

Thank god I got divorced immediately prior to the the build...

Looking forward to the results. You should see well into the 500whp range with cams

Have had the opportunity to drive her this weekend for many miles and I have to say it feels GREAT! The stalling issues (drop in rpm under load) have been fixed thanks to the tuner sending me map updates. Only thing to be done now is to fix the boost spiking issue. Will update once this is taken care of.

Glad you are getting the tune worked out! It's got to feel good to be driving her! What gears are you seeing boost spikes in?
