Well i finaly got a chance to race with the p5xlt you built for me yeserday and i must say im impressed. My tune was way off and i was finishing up the break in. I had alot of people asking what I had done to it and said it was very quite but fast going down the straight.Funny thing is,i wasnt even 3/4 throttle down the str8 and didnt have any problems from getting passed lol.Well today I went out in the yard and put a better tune on the low end and got rid of a 3 stage idle,then tuned the top some but not to much since I wasnt on a track.All I can say is everybody better watch out next week because she isnt quite anymore lol.Oh yea and i dropped in a 7.5 vent..This engine rips hard!!!
