Crazy spiking after MP install
 

Man.. i guess my weird boost patterns is solved with the MP install. now i have a full upgraded exhaust. Before i was seeing 10-6 patterns. now i get 11 on primary and spike dramatically when secondaries kick in to 13psi. Of coarse i quickly let go of the throttle. BUt still can't really tell for sure if i have steady patterns. anyway to fix this spike?

I'd get a boost controller or enlarge your wastegate. Or put your cat on until you upgrade your ECU. I don't want to hear about another FD with a blown motor.

what about cheap preventions to regulate boost? Bleed valve mod? and how much would porting the WG cost? Also i heard about a pop off valve but not sure how u tune it to the boost u want it to release? is it setup like a nob like a manual or is there actual dials for certain psi?

ok what ecu are u running....u have an ecu dont u......

ok options
if u have pfc it can tune out the creep
bleed valves may help but if its creep. ull have to enlarge the wg....

enlarger the wg...if u do it ur self it will take basic tools..abt 4 rs to pyll and dissasemble the turbos from their manifold..then abt 1-2-3 hrs with a die grinder with a carbide de-buring bit...


fab a plate that goes in the exhaust..but only has a 2 1/2 hole in it...

I have a few plates available that I used in the exhaust system with 2 1/2 and 2 1/4 cut outs made of stainless steel.

Anyone interested?

p.s. I ported the wastegates and no longer need them.

READ HIS WORKS BEFORE YOU COMMENT PLEASE

He said spike. To fix spike you either need a new pill on the precontrol line or an adjustable valve in its place!

well since he hasnt run it to redline...he may be creeping......

Most likely creeping. Try the www.dawesdevices.com boost controller. ;)

i just pulled the pills off today... now i'm not getting crazy boost readings. i'm running at a very safe boost level...actually too safe =(. running 8 psi all the way. i might put in the bleed valve and hope to raise it back to 10...would u guys reconmend going back to 10. would the Dp/mp/catback affect the fuel carve at 10 to be in danger of detonation?

leave it at 8psi an ecu is a hell of alot cheaper than a new engine ;)
