If you are trying to tune your car NA, it's nearly impossible to get repeated good results from an eTune. NA tuning is about extracting those less few whp out of the car, and each engine is setup is slightly different. With a turbo car, it's a different story. We do dozens of etunes on many different platforms, such as Evo's, Sub's, GT-R, 370Z's..etc..etc.
Your best bet is contact a shop that can you setup with a complete package with an Osirus license, and a custom dyno tune. PM em if you have any questions...we are located in the Atlanta metro area.
