Well guys i finally broke down and bought a new cam and springs and had allen install it last thursday. 200/222 .580 lift and 114 lsa. After his tune and a few runs we were able to see a 40hp increase at the rear. Since thursday it has felt like it has gotten stronger. I love the new cam on how it sounds and runs. I cant wait to take it to the track and see its numbers. But i may get a stall before next time i go to the track. I am now putting down 274 RWHP. I love hearing the truck scream down the road at 6000 rpm's.
ALLEN IS AN AWESOME TUNER.
Thanks goes to Allen and his brother and father in law for installing the cam.
I believe it was his father in law.
Allen offered a good price and great service.
