I am in need of a good shop that still works with NIStune in the Denver/ Lakewood Colorado areas. My car is currently running E85 and I want to get it switched back to regular gas until I can afford the AEM V2 and all the sensors to make my car a true Flexfuel car. I can only find one gas station that has E85 anymore in my area.

My car is currently running an AutoVaugh Performance ECU.



I've talked to the guys at CarZ and Racing Trenz and neither shop uses NIStune anymore. Any information would be greatly appreciated.

Thanks.
