I'm down in Texas and there is only one nistune tuner in the state. I called to see how much a nistune flex fuel tune would be and the prices are ridiculous. He said I'd have to get a 93 octane tune, the e85 tune and then a mixed tune. I barely have the money for one tune, because of the holidays, much less three tunes. They are giving us almost 2 months off for Christmas. If I can get a good tune for R34 N1 turbos I can adjust for my z32 mafs and 1000cc injectors, I'll share my flex fuel tune.
