second tune i was told to"give it more time to learn".so i put it in right before i drove from new york to virginia,lost 2 MPG and the truck was no faster,only improvement was the top speed limiter was bumped up.
last tune as soon as i put it in the shift point were stock RPM and the top speed limiter was stock.
this whole experience friggin blew ***,worst money i have ever spent on an"improvement".this ended up costing me UPS charges three times and about 10 long distance phone calls.
must be you have to be from texas to get a good tune from allen.
oh yea i also put a trans go shift kit in and was told to put two washers in the 1-2 servo now with out the "tune"my tranny feels like its going to come through the floor on the 1-2 shift.
i have talked to brian at PCM for less and he has a good sales pitch


,but after all this crap im a bit gunshy of ****** with this any more.
i will say allen did refund my inital cost of 500.00 but i ate the time,calls,and UPS charges.
