Innovative Tune Differences

[gharvin]

I have a question regarding innovative tunes. I bought an X3 with eric's street and extreme street tune. I am currently running the street tune and hand calculating my fuel mileage. It has improved over stock. I am debating on the next tank of fuel to run the extreme street to compare. My truck is stock as for the motor but has a 3" lift with 325/60/18 tires. I had Bill at PHP reflash the PCM and he corrected the stock file for the tires.

I do not hot rod my truck and drive very conservative. My concern is am i risking anything driving the extreme street tune with a stock truck. Will i see a better increase in mpg?

You will love extreme street on a stock truck. I ran that tune for about 40k on a stock truck with no issues.


Disclaimer: Mileage increase depends on right foot usage after tuning

so you had the speedo corrected for the tire sizes??? but ya extreme street is way different i like it way better. i had him flash the FICM in mild the lowest tune and was thinking about getting then next step up. to see what it does. i didnt even know what the ficm tune did when i did ti too lol stupid mee

I don't think he corrected the speedo as it is controlled by abs, I think the tire size adjusts the shift points only.

If bill adjusted your stock file and you gave him your tire size your speedo is corrected
