This is the first vehicle i'v had that i'v wanted to tune up and put some mods on cai headers exhaust the usual stuff...but i worry about mail order tunes because i'v heard stories of guys ordering tunes from the south where the air is thinner and dryer and putting them on there car up here in the north and destroying their motor in a matter of months.
There is one dyno tuner close to where i live i sent them an email this morning to see what they can do and what tuning programs they use but from their website it looks like diablosport, but in the mean time figured i ask you guys the questions as well. If i order a tune from 5star and put it on the truck can any tuner plug in and modify that tune? so i can keep the work mike has done with shifting and the off road mode and get the A/f adjusted to my area or would the tuner have to start right from scratch? Does a tune rewrite the whole ecm or just the parts that have changed?
