it seems like every time i make a good pass my car hits boost cut in 4th gear right before the 1000ft mark. i've been 11.06@108, 10.84@120, it's really irritating. its something with the computer cuz i looked at the datalog and the boost drops while im still 100% tps. its not over boosting. it's sticking right at 21lbs of boost

 

What do you have the boost cut set at in the ROM?

On most softwares you can log if you are hitting boost cut or not in the data display.

 

the boost is set at 21 and the boost cut is at 25 it usually only spikes 22.5 at most

 

If that is whats happening, it is boost creep, not spike. We can't help you without more info. What are the datalogs doing exactly??

 

im no tuner or anything. i just look at my datalog and all i can tell you is its not hitting 25psi which is what my hot boost cut is set at. it stays right around 22 psi at most and it starts losing boost around 7500. that's all i know. lol

 

nobody is going to have any idea until you post the datalogs, because this could be a number of things, your AFR?, injector duty cycle? can your turbo even support the boost? But it is definitely no boost cut because when you boost cut everything just comes to a sudden stop except speed, its not gradual and pleasent haha, scared the crap out of me when it first happened.
