ok so my truck runs strong when going through the gears but when im in 5th gear and give it some wot it doesn go any faster. it takes a good 10 seconds to go from 60-90. is it something in the p pump that isnt allowing fuel at top end?

 

at them rpms you may want to upgrade to a 4000gsk. i recomend a 4k kit fright from the start and dont mess with 3ks. youll want the 4k anyways. and is your timing stock?

 

Tune the AFC. You got the air to make er scream. 4000's would be a great bump too.

 

with mine it doesnt even take 10 sec to go from 60-90 at about half throttle. thats bout all i can give her in fifth without slippin the clutch.
