Thanks! Back when I was young and stupid everyone was telling me to de-screen the MAF so I did and my truck ran like crap. I researched the ins and outs of how the MAF works and there outlined above is my Freshman year research paper, the topic was up to us. I shortened it QUITE a bit to fit it on here but basically I left the important points in.

 

This is a cam that came from comp cams as a kit with springs. cam part# 54-452-11 gross vale lift intake.520 exhaust.524 lobe lift intake212 exhaust216

 

I Took Out The Rocker 1.85 Trying To Get To The Root Of Some Of My Problems. I Was Hopping The Truck Would Run A Little Better ,not Happin. I Put The Stock Rocker Back In The Truck Runs Ok But There Is A Hesitation Around 50-65 The Idle Is Fine And When I Floor It She Doesnt Skip A Beet. I Think The Truck Need To Have The Computer Flashed Stock And Start Fresh.

 

I would contact DC Justin @ Blackbear Performance. He is in the DC area (!) and will be able to get the truck running correctly.

 

I Got A New Map Sensor And The Truck Doesn't Run Any Different.

 

did you get a MAP or a MAF?
