I am new with HP Tuners and I am looking for some nice tuning that bring more power to my truck. I already got the stock file, the only i modify is a speed limited. I want to change some parameters to get more power but like i am new in this i don't know exactly what need to be change to get more power in my truck. If anyone already have a L5P with a nice tuning that bring some power and whant to share or give me any advise on how to make a tuning for more power, please post it here. Also I am willing to pay for a file with a nice tuner.
