VF tune initial reaction

Hello all,
Just loaded the 04B81_reg_35_Thx_4.88 tune. shifting, throttle and overall power is mich better, im happy. Not entirely sure what the differences were between 33 and 35, and why some files specified the tire size and some didnt though...

 

The ones without a tire size are Stock (31in). From the folks that I have talked with, you want to be conservative with the tire size tunes. If you're anything over stock, go with 33in. If your close or at 33in, go with the 35in tune.

 

I have the 265/70/r16 tires... should I be using the 33 or 35?

 

That's Stock 31s. If you haven't changed them (still Standard Load (SL) ), then the Stock tire size tune should work for you. If you want the shifts to be a bit higher in the rev band, test out the 33in tune after this first flash fully settles and you get a feel for it. About 500mi.
