I have tubular exhaust mani, 3" 02 housing, full 3" catless turbo back, intake, 3.5" front mount, licp, mbc,big radiator and a walbro 255 in the tank. I believe ivey has a dyno jet not a mustang. So on a mustang it would be what 10-15% lower than the 310 on the dynojet right? I coulda swore id be at least 340 wheel on a dynojet. Oh and I have an viii.

Thats what im thinkin everyone says stock injects are fine up to about 400hp. My buddys got the same car as me, same mods but with gsc s1 cams and meth/water making 390 to the wheels. tuned at the same place on stock injectors. He said his duty cycle at the top end is 95% so im thinkin they werent the problem. I also had them do a boost leak test before the tune and all was good. Only thing I can think of is, it was a busy *** week right before a holiday weekend, and they flew through my tune just to get me out the door. Maybe flashed my ecu with a tune from a previous car with similar upgrades and tweeked it a little from there and went on to the next car. I left the shop believeing I was at 25lbs of boost if I knew I wasnt I woulda asked further into detail but they dont remember now what the situation was 6 months ago.

I don't think it would be a previous cars tune being the car wouldn't act right. With the addition of cams yeah your gonna see more power, but this isn't your case. I would call the shop and have them look over your tune again. I agree the #s are low, but maybe your car just doesn't make that kinda power. In that said maybe they forgot to flash the last flash to give you the 25 psi of boost you think you got. I would have them look at what they gave you to whats actually in your rom to see if it matches. 95% injector cycle is a bit high and to me I wouldn't want to run that all the time. I would definitely bump the injector size at least one size if your not going to a larger turbo. Another thing I would suggest is let them know they told you were tuned to 25 lbs and the car does not see it. And give some bull**** excuse that you haven't been driving the car and never really noticed it till now. All in all either go back to the shop and ask them about it or just give tscomptuned a call and he will give you what you need. I mean I don't mean to plug Tom or nothing but he is the only tuner I will allow to touch my car.

I turned my boost up 1psi on my mustang an my car ran a half second faster! Depends which platform your on: Playstation or Xbox. Seriously, don't touch the boost controller without experience unless you like fixing ****.

He will remote tune your car from home. He isn't really a big shop. Trust me he is one of the best tuners if not the best tuner on here. I would send him a message on here, or email him off that site. Trust me when I say it is well worth it. Look him up on here for his work.
