My car has K&N filters, downpipe, and catback. It just recently started to boost spike to 15ish psi on the transition to the secondary turbo, this scared the crap out of me so a friend of mine gave me his MBC cause he got a greddy specII. So i put this on via the robrobbinette site and it went smoothly. I did not do the pre spool though. So i go out to tune it back down to 10psi and it didnt work. Finally i turned it all the way down and nothing still spiked to 15psi.



What the hell should i do?



thanks guys

Do you have the boost controller plumbed in to the wastegate actuator? If so then did you remember to cap the far end of the actuator?

i did it via this picture..

with this boost controller..

off topic, jeez that engine bay is clean. :(

On the wastegate actuator there are two nipples. One should have the line "out" from your boost controller plugged into it. The second nipple needs to be capped in order for the controler to work. The picture you posted from robinettes site does not show that.

its the nipple facing the engine

but my boost controller is going to the right nipple right? where does the nipple im going to cap lead to?
