Performance mods?
 
I have a 99 grand Cherokee limited with the 4.7. I have the k&n fipk kit, flowmaster super 44 muffler, cut the cat off, and that's it. I just want more power without having to take the motor out. I had a superchips flashpaq on it but I took it back because it barley did anything. Please leave tips and suggestions! Thanks guys!

you want it to go faster or what??? really unless ur wanting to spend alot doing other mods to motor u could try a bullydog programmer and see what u can get out of it they are available on ebay for around 300 its computer u can hook up and does tons of stuff and helps u monitor the engine very well i was gonna look into getting one but not sure yet

Flyin'Ryan did mine and I immediately noticed a difference on takeoff. Puts some more life in the 3.7 at least.
