Ok I'm having a problem with my boost, but only in 2nd gear. My first turbo kiks in , but when my 2nd turbo comes on line it drops to 5psi . In every other gear ithe boost is fine. I just recently installed a profec b i have the dip switches set to normal that is up down up down. Does anyone have a clue what is going on.

 

bump anyone

 

ok, i'll bite.

list mods and provide us with a better description of boost pattern through your gears from 1000-7000 rpms.

also re-read and check your install. there are so many threads of problems installing the profec b.

 

i have a pfc profec and some guages.in 2nd my boost starts at around 2k rpm I start to loose boost at around 4k rpm it looses boost until it gets to 5lbs then it stays at 5 all the way to redline.

 

ok. that wasn't very helpful info. what boost levels do you see on the boost gauge throughout the rpm range?

and why do you have a PowerFC and a Profec but no other mods? Don't understand why you have that on a stock car.
