I have a stock LS swap in my EG and im using the stock p74 Basemap on the S300, havent changed anything but the launch control. At full throttle sometimes in between shifts it will sputter/cut out... feels like its getting fuel cut. It doesnt do that with a stock ECU. Not too sure whats going on. If anyone more familiar with this could help me that would be great.

Thanks, Brian
