[QUOTE="Matts50, post: 575914, member: 11475"] Looking for some opinions before I start tearing into vacuum lines. Recently purchased the car and installed a boost gauge so I do not know much of the history. 1) At idle, I'm getting, at best, 2" of vacuum, but mostly 0". 2) I'm only seeing a MAX of barely 1psi at 5500rpm in 3rd gear. It's a 6psi set-up, but with my set-up, I was expecting to see around 3psi. 3) I'm not sure if this is related, but when the car is idling and I stab the throttle, it lags quite a bit and doesn't react to the full amount of throttle that was given to it. 4) Through research I'm pretty sure this is completely unrelated, but the car HATES to start when hot and sometimes won't even start with the gas pedal to the floor. I thought this may be related needing a chip/dyno tune. Let me know what you guys think. Worse comes to worse, I'm gonna replace a bunch of lines and make sure they are fastened well. Thanks, Matt [/QUOTE]
