I just put this together real quick showing a comparison between our Stage 1 TT Kit on E85 vs. our GTR which has a Y Pipe and EcuTek tune. The GTR was tested on the same dyno (2WD mode) as the 370Z. This chart should put all of us GTR owners with mild mods on notice. DO NOT mess around with a FI TT 370Z on a roll. You will pay dearly!!!
