So i took my car to the shop, and i got my new fuel pressure regulator on, and my car runs great now...

only thign is that now when i hit 9lbs of boost, my car jerks slightly so i let off the gas.

any ideas?

Thanks in advance guys!

 

btw, i am very well tuned at 24psi.

it boosts normally until i get to 8/9psi...

any advice would be great!

 

Did you install an adjustable fuel pressure regulator? If so, what brand? Also curious if you have a fuel pressure gauge, and if so what is your fuel pressure at idle? Please post your complete modlist.
