Had my 2008 6spd tuned at L M R in Houston today.432 rwhp Texas speed headers x pipe no cats.the rest of the car is 100 % stock with NPP mufflers.It was raining all day so I have not ran it much.It sound Great.
Only headers and Tune. I asked about the numbers, they said it was one of the highest they seen on that dyno.I would like to run it again somewhere else and see the numbers. I did the install and did not buy anything from them just paid for tune.
