what boost controller are you using? or how are you regulating your boost? wastegate adaptors or manual boost controllers, etc. and are they working for you? hahaha

igotta greddy manual boost controller, Like most boost controllers, it allows my boost to creep. thinking of going electronic soon,

 

anyone use the turboxs manual one?

 

it's a pos boost controller.

 

Wrong. Your undersized wastegate is causing boost creep, not the boost controller.

 

u can put in a regular valve in there but if its not spring
controlled than u will boost higher and the boost will be dropping as its spooling

 

got a ported wastegate on the stock s4 turbo, running a greddy profec a. the earlier model. ($250)

 

old HKS EVC II or something... ive had it on my car for about 5 months(my car's been down for 4), but didnt have it hooked up until now due to boost creep problems. i think i overpaid for it a little($200) but an electronic boost controller is way better than a manual.

 

i made my own MBC and it's great. Wont let the boost over the set amount... but to set it... takes a little bit of test and tune time.

 

I got a greddy profec-B(the good model)

I like it, you can set a high boost and low boost and switch with a hit of a button. You can also adjust the sharpness of when the boost really kicks in.

With you free flowing exhaust you need to port your wastgate if you havent. Boost cotrollers are really only boost increasers.

 

well i just ordered the turbo xs high perf. boost controller. it's ballbearing and ****. lol. it should work fine. it's not the cheap model. a step up. my wastegate will be ported to all hell so i should hope not to creep. thanks for you help guys!
