1.) i was wondering what you guys who have 2.3T's get for mpg's and approximately the power your pushing.

2.) Is there a way to have lets say 2 different A/F tunes, lets say one for performance and another for economical driving.

thanks in advaced

 

so what number comes after b?

 

Don't know. But at 2.3L of displacement and with it in good tune I'd think mid to upper 20s would be the norm. That is unless you had a radical cam.

Yes. You'd need either a flip chip or a flash device. But... part throttle A/F and WOT A/F can easily be controlled with the same tune. If you had it tuned properly for one grade of fuel.. a single tune would do both.

Now if your like me and like to use a race fuel at the track? Then two tunes would be needed for increased timing and possibly increased boost.

alright, thats clears up quite a bit. thanks a ton

 

My 2.3T in the 94 has achieved 27mpg doing 90% highway driving. It usually averaged 21-23mpg, and that was not taking it easier with her at all.
