I ran the ESS Tune with the Akra Evo before I got the ESS VT2 sc and loved it. I removed the cold start as well and was very happy i did so was everyone who lived close by
the tune def makes a difference and was very happy with the end results. the car shifted smoother and was a lot smoother through the power band. Good luck with whatever you end up doing. Make sure to really search the forum before you make your pick on which tune you go with. there is a ton of great info on here. GL
