I probably would have made room for some JBA Longtubes in the budget, if I could have found a Y pipe when I first started sourcing parts. Seems to be sold out everywhere I looked because they were apparently discontinued. Then I kept reading about issues with engine bay temps and knock sensors causing other peoples trucks to jump timing. Since this is my daily driver for the next couple of years I decided to be a little more reserved. Probably down the road, when I am not relying on this as my daily I will go FBO.
Since you are not doing headers you would probably benefit more from the .5HL V2 vrs the 1.5HL V2

I'm getting the low lift cam.

From Greene Racing's page: "
Stage 1.5 LL VVT camshaft line.

209/226 just like the Stage 1.5 HL v2 but with slower ramp rates and lower lift to be safe with stock springs. Lift will be .550/.550"

Hello, I am having P0303 code also. The truck is runnig fine no hesitation or any miss fires. I have changed the spark plugs changed coil positions(no change). Even had a mechanic do a compressions test(good compression). I still getting P 0303 code. The mechanic pulled the valve cover found the exhaust on #3 not moving as much as the rest of the valves. I am hoping that is the problem. Why would the truck still run good if the exhaust valve is not working properly ??
