I installed the Air Force One and it's awesome. After I installed it I noticed something weird happening when starting the truck while it's cold. It used to be the truck just started with no hesitation. Now it has to turn the crankshaft a couple times before it starts. I noticed this hesitation only happens when the engine is cold. When it's hot, it starts right up just like before. I double checked to make sure my lines weren't blocked at the intake becuase I know that can cause a rough ride.

After the engine is started everything run fantastic. No hesitaiton. No rough idle. Nothing.

Has anyone else experienced this?

 

IS ENGINE CHIPPED FOR THE MODS/

 

you don't need a chip for an intake only.

 

Well I've had the air force one on for about a month now. It works great. The truck mostly starts normal now. There's not much hesitation. Every now and then when it first start it will act kind of rough for a second or two. It does that while in idle and only when the engine is complete cold. After that, it runs great.

I'm really noticing big gains across the board with the AFO. Mainly second gear seems to really have come alive. With the gains I feel I wish I would of done the AFO from the beginning.
