Comatose Posted September 24, 2014 Share Posted September 24, 2014 I've tried to search, though I don't know how to put it into words I have an r34 GTT with a 3" turbo back and Elec boost controller (11.5psi with stock turbo and sidemount) When I'm in second gear and I have my accelerator half way slowly gaining in the rev range, suddenly the accelerator will cut and it feels like I've slammed the brakes on for a second - the slip light does not come on It's pretty scary when it happens so I wouldn't mind fixing it, if anyone has any suggestions?

Ben C34 Posted September 24, 2014 Share Posted September 24, 2014 (edited) Too much boost. Boost spike causing the "boost cut" to occur. Drop boost or gain setting and report back. Or you have a boost leak. Or a combo of both.

Comatose Posted September 24, 2014 Author Share Posted September 24, 2014 Ok sweet, I will try to drop the gain. Where does the cut come from? Ecu or boost controller?
