Power Surging

[mayhem]

my ba 2 has a custon 10 psi tune but lately I noticed it struggles to make 9 psi I changed my panel filter to a re usable lukey filter this gave me .5 psi gain as my dumbass mechanic didn even look at tha filter last service and it was chockers so now with new filter and no audilbe leaks I make 9 but in fourth when its boosting the car surges its not as progressive as before its been so long since ive given it a hit I dont know how long its been goin for and every time I take it to my tuner he wants to sell me some over priced exhaust saying tha will fix all my problems so anyone who can recomend a good tuner in western syd that would be tops

mate have u got bigger injectors?

if not u may be experiancing maxed out injection duration

I would be carefull if that's the case u will be leaning out and could destroy the engine.

just a thought. what other mods have u got?
