Hey gang, I have a question about my recent KB 2.8lc installation. Last week I installed the stage 3 kit from KB. It comes with a flasher and a loaded tune for the car (2008 GT500). Car starts right up, idles good and drivability is good. The only problem I am having is at WOT. At about 4000 rpm, and starting at 50% throttle, the car stumbles and bogs, basically falling on its face.
Car ran perfect before the KB install with my TVS and Lund tune.
HERE'S MY QUESTION....
The KB stage 3 kit is designed to be installed on a basically stock GT500. The tune that is included is also for stock components...
When I had the TVS I had installed 13-14 injectors (56#) in the car and figured they would be fine with the KB, but now I'm thinking if KB's tune is written for the stock injectors, wouldn't that cause some drivability issues?
Any help is always appreciated.
