Your tuner should have already asked you that. Keep pulling a degree or two out until it stops. Link to comment Share on other sites More sharing options...

Keep pulling a degree or two out until it stops.I have 2nd cai with k&n filtervalve springs are donefull 3 and a half exhaust systemand edit with custom tuneas for when it happens it is around 4000-4500 rpm in 2nd gear. I dont know about 3 and 4th as the clutch isnt up to it at the moment but I new one is on the way.as for the tuner we took it for a test drive when I took it back so he could find out for himself and seemed to have fixed it but has reappeard Link to comment Share on other sites More sharing options...

If you still have the stock pump it could be running out of fuel.... Link to comment Share on other sites More sharing options...

Generally most people upgrade the fuel pump around 270-280, its just to make sure you don't get this problem Link to comment Share on other sites More sharing options...
