I'm with ramble here. I'm not new to piggyback tuning, I had an apex i fuel management piggyback computer on a 600 whp car and I didn't liked the way the piggyback system works, fooling the ECU by giving false sensor readouts for the computer to compensate with more boost and fuel. Needles to say I change to a standalone setup (MOTEC)

By the OE tuning flash been only a $136 diference from burger tuning stage 2 is a no brainier for me, and hopefully OE also changed the cooling maps like Dinan, that will be a big plus. I respect others decitions in choosing burger tuning, I guess that is a good thing having different types of tunes to choose for. To each their own
