Well i finally did it! Was so tired of wanting more power and MPG that i went ahead and gave myself a Christmas present and bought it ! I will update on performance an MPG as the computer learns. So far i did find my stock intake had a mildly blown plenum gasket and numerous coolant leaks. all fixed and only issue i had with the install was the fuel rails and the guts to cut the crossover tube as it came with a hard plastic on and could not get it to fit si I installed 100 psi rubber fuel line instead. Took it out today and only issue was my TV cable needed adjustment as it was shifting really late and downshift with pedal almost to the floor which i didnt like. will post pictures once daughter loads them. Ha ha laugh it up i know. today my scan gage said a change from 10MPG to 13 today and the truck runs really smooth and quiet. except my exhaust note is just mean now!!!
