2nd gear boost problem

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.

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.

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.
