Help with soft pull after mods

[Tasigur09]

im about to give up. Ive sent it to 3 shops and thr dealership. Done the smoke test. Check for codes. No leaks. Given me various reasons why its working fine and the torque is there. Im beginning to think I might jusy be crazy but I know I lost the shove that I had when it was stock and the harder shove it had the first few weeks after installing the mods. Im located in south Florida. Ive feel like ive been to most of the performance shops there haha

Are you sure your not just getting accustomed to the power?

Why not put it on a dyno and find out exactly where the power is at?

Maybe we already covered it, but are you using quality TopTier premium fuel (ideally 93-octane)?

Put the damn car on a dyno.

Or, download an acceleration app on your phone and check the times the car is putting up.

With the app I'd be focusing on the 1/4 mile trap speed, that'll remove traction and launch variables because the power will still show up as mph at the end of 1320.
Just find a safe place at a time that no one is likely to be around, including cops.

Your trap speed can be compared to established speeds from reputable sources, should be a few mph higher than stock

if your in south Florida; and you really feel their is an issue with the car go see boosted 6 or temis Motorsport. They are both VR30 experts and in Pompano beach; Temis motorsports also had a dyno.
