Well ever since my 636 crotch rocket highway pulls, the truck seemed to be down on boost. Next was on the dyno where it would only make 16psi off nitrous, then last night at the track was 15 dropping to 12-13!

After double checking for boost leaks, I headed home. Once home I hooked up my pressure checker to the turbo, all was good there. So next I took the wastegate off and put air to that. All good. Thinking sh*t, I hope a didn't bend or melt a valve. So I did a compression test, starting on drives side. All looked pretty good for 105k miles and light abuse.

Then to my happy surprise I noticed the old JBA header. Ill be hitting it with the MIG today, maybe back at the track tomorrow to see if she's fixed up.

Glad its not something big, now u need to go back to the dyno

 

Put a stocker on that bitch and run with it

 

Glad it was a simple fix. I want to see it back on the dyno now after the fix.

 

This! Unless there's a reason the stock manifold wouldn't clear(don't see why it wouldn't).

 

Glad it was a easy fix for yah man..

 

losing faith in the old 4.8. she's good for another 20,000 miles. glad to see nothing major wrong.

 

Damn man had me worried there for a second (like when your hero gets beat my the villain) lmao. x3 just throw on a stock piece and roll with it. Maybe you will get even better times!

 

dang you got off lucky, atleast it wasnt nothing big..

 

Lmao, I have that exact same compression tester.
