Bay Area,
Ok so my frount mount started leaking so i took it off and put my sidemount back on... i turn boost down to 8 psi and lean out .. drive for a week or 2 like that, then i decided to up my boost to 12ish.. but everytime i hit aournd 10 psi of boost my car makes a big buck , even when i am soooo ####ing rich.. i logged it and im not knocking...it has to be fuel cut.

well anyway i was scared if ####ed something up so i took my car to prostreet in hayward and John from prostreet helped me. He tuned my low throttle then we after we were doing hi throttle and it wouold buck , so he checked out my engine , he though i had a blown HG, so i went home and changed my oil... no problems there... Now what should i do? any ideas?

my b16g is new so its not leaking.. i have magnacore wires on and NGK plugs which both have around 30kish on them? is it possible that a wire/plug went bad? how do i check wires? Today im going to check my plug gap to see if there are any major discrepencies. any info appriciated. Thx
 
fixed my intake leak... guess itw as an intake cover cap popped off... but ya now i gota re-tune.. argg!
