Hey guys, been busy lately haven't been around since the blazer project was finished (been driving!).. thanks to everyone that helped me in the summer with the stupid little questions, now i'm here to answer yours!

Am running an MPFI 2.8 out of an 86 camaro, kept the multiport, also running Borg-Warner T5 out of the camaro

Was wondering if anyone else has problems with their idle dropping (like 400-900 RPM!) when they apply the brakes?
I think it has something to do with the vacuum demand of the blazer's vacuum brake booster, but well, lets just say my truck idles at like 1,200 RPM so that it will be at 750RPM when i put on the brakes, otherwise it would stall constantly..

Any ideas on how to fix this problem? Any ideas on the cause?

Thanks guys
