Some of you know that I was going to keep my charger stock, but I had a tune put on my car and it shifts great now. I did not get to be there when they did it so I have little info on what was done. I was told they remapped the pcm but I did not get a tuner for the car he used his lap top to do it. He said try it out and see how it works and not to tell anyone that he did it
Stock it was 304 at th RW and with the tune 344 at the RW 
I took it to the GTG and it ran good like I said it shift hard and fast but I can not tell much more HP I drove it some that night and on Sunday, I was going to run it one time with a bud that has a 2007 Charger we started at 40mph and ran to 120mph at that point my car shut off 
It took a bought 10 times to get it to start. I took it to dodge to put on a new state inspec on it and the check eng was on so he ran a scan on it and wiped out the code for bad fuel pressure now it will not shift as hard or fast and a littel down on HP do you think that it removed the tune from the car
