add MBC to 850t or not

Post by **phils94850** » 15 Jan 2010, 15:18

i added a MBC to my other 94 850t and it really woke her up. The 850t i have now is still all stock basically. I turned the wastgate rod in about two turns to help with take off.

Ive read mixed reviews on adding a MBC. My boost gauge ( factory ) goes just a bit into the white. If i add a MBC and get a aftermarket boost gauge, whats a safe boost level to turn it up too ? Im planning on getting a tune soon also.

I wouldnt go over 12PSI. make sure you have a good boost gauge before doing it. you dont need a mbc. I just used the wastegate rod.

+1. im running abour 10-11psi. remember @ 14ish you will hit fuel cut with the stock ecu. so @ about 10-12psi your safe and still getting some extra power.

I'm running 15psi with stock internals. See this manual boost controller topic for more info.
