another ?

just noticed today looking over my invoice from my tuner, that he had flashed the pcm for 3:42 gears and 26" tires!....I had told him originally that it was 3:08 gears and 28" tires...what will this effect other than the speedo?? I really dont want to go through the hassle of shipping it back to be fixed....

Re: another ?

It will also mess up your transmission shift points. I would send it back and have them fix it.

Re: another ?

I'd think so...those are minor changes. Might cost an arm and a leg tho!
