This Weekend I Was Heading To The Dunes With 4000 Behind Me I Hit A 7% 1.5 Mile Long Hill At 65 In Od. I Went About 3/4 Mile And It Started To Cough. It Would Run Pop Run Pop. It Was Kind Of Like A Backfire. I Made It Home Allright But What Happened. My Post Pyro Never Hit 900 While This Was Happing I Have No Boost Guage Sry. I Know Its Not A Plugged Up Airfilter. My Mods Are In My Sig. Btw I Was At About 3/4 Throtle

Fuel pressure test ?
Fuel filter ?
Drain some fuel into a glass container , to see if there is any contamination ?

 

Throw a new filter on it and see what happens. If it keeps doing it, plumb a piece of clear hose in at the lift pump inlet and see if you are sucking air.

 

K Ill Try The Filter Tomorow

 

Could it be too much timing?

 

thats the thing i havent messed with the timing yet

 

Oh ok it says timing bump in your sig..
