chato Posted November 22, 2014 Share Posted November 22, 2014 i'd check for boost leaks and things like loose heatshields that could be causing false knock as well. Link to comment Share on other sites More sharing options...
fahr_side Posted November 23, 2014 Share Posted November 23, 2014 I was running stage 2 previously but that was with an invidia high flow catted dp. Stock exhaust though. I don't really know how to raise the boost targets other than a new tune. Right? Cause I could run a protune on a stock setup right? Have you tried running the Cobb stg0 or stg1 maps? You might also try unhooking the waste gate actuator from the arm to see if the flapper moves smoothly.

Kicker_64 Posted November 23, 2014 Author Share Posted November 23, 2014 Yeah I'll check for leaks. I ran stage 1 for awhile after I put the hardware back to stock but still had bad numbers. Is stg0 the stock map? Yeah I unhooked it and it the wastegate flap moves smoothly. Link to comment Share on other sites More sharing options...
fahr_side Posted November 24, 2014 Share Posted November 24, 2014 Stg0 is stock boost and fixed timing.
