what all did you have him do 04blackGMC? i just got mine and cant tell at all but the shift points are higher and a little firmer. it actually seems sluggish and not very responisve driving. just wondering can you tell much difference?
thanks

just got mine today, tune feels real good.... you guys say the tune will get better after about 100 miles on it?

 

the tune definetly gets better with more miles... when I first got mine, I was thinkin' the same as everyone else... noticed the more agressive shifting and extended shift points... but as for power... I would get on it.. and it would just kinda do like the stock PCM. Now when I get on it... she'll light up the tires all the way down the road. I'm just glad for the free retunes... got a new TC to put in ... just havent had a chance.. have to send it back to him when I get around to doin that.

 

Well im on my second tune and it feeels alot better now.
