Just picked up a predator tuner. With a smaller upper pulley running 2-3 lbs over stock decided to plug in the performance pulley tune. Major hessitation going on. My boost gauge will flicker for a second or two and then it will kick in. Normal???
I think the computer needs about a 100 miles to get used to the tune and learn my driving pattern. Based on when i disconnected the battery one time my truck ran like poop for about 100 miles.
Should i screw with the timing and fuel. Thinking i should add a touch of fuel to come up to the boost added.

 

I would get with Sal at PSP and get a custom tune for that thing, don't bother with the tunes that come with the predator.
