So i dont have the v10, but just loaded tunes from 5star on my 6.0PSD, i had Mike change the street tune to be a little more conservative, HOLY SMOKES
comepletely wakes up the van, shifts are a bit more crisp and firm, just putting around town it drives the same as stock, hammer down on it and once the turbo lights it takes off!
Once i provided Mike with my strategy code, i got all the tunes emailed to me within a few hours. very pleased with 5 star tuning. would have no second guesses about recommending 5 star tuning to ya.
