the AEM piggy back setup will be for E50 or Race Fuel purpose only, That's if I cant figure out a way to run E85 on a budget, I have overcome worst obstacles than this! On my race bike 04 GSXR1000 I was the first person to break 200whp on stock parts and 93oct pump gas and that was on my MustangMD dyno that always reads conservative, Took Same bike to D&D performance dyno and made 214whp. Keep in mind that's a N/A 1.0L motor on stock parts. Its all in tuning and overcoming obstacles. I don't like to sit around and let everyone else have all the R&D fun and then buy their products knowing I could have done it myself (maybe even better) and then moan and groan that no one offers us anything because our cars don't say EVO,STI,VTEC, etc.....There a lot cheaper faster cars I could buy but none at this moment that peak my interest the way this car does!!
