Boost issues..

[niterydr]

uhh...could we get a mod's list? (so and so's car, built motor, etc) hardly lists whats done to the car, and more importantly whats missing to support additional power.

I have the same problem. But I have done the boost leak test over and over and I get nothing. I don't have my air/fuel guage in yet so i can't tell if im running rich or lean. It will jump up to 15 lb's and then slowly crawl down to 12 or 13 lb's. Could it be that the stock turbo just really sucks.

I also have that same problem but mine goes to 15 then down to 10 psi. It started to happen after i'd install my hks ssqv bov. I don't think that it's leaking because i'd did a boost leak test also and nothing show up.

It might be that the stock waste gate spring just sucks. It all started after I did the BCS mod. Before that it would hold a solid 13 psi. Now it releases the boost right at 15 lb's and then back down to 13 lb's. I'm hoping it will all stop after I get my 550 cc's and evo 16g from forcedperformace.com.

Every paycheck is one step closer.

I'm glad to know I'm not the only one with boost problems.
