Looking for new upgrades!?
I have a 99 grand cherokee limited, 4.7, i have the main bolt-on stuff, k&n intake, flowmaster exhaust, had a superchips flashpaq (took it off), but in looking for more power. Any ideas?

i beleive you can do 4.7HO intake stuff. if that dont work then idk maybe go open source tuning.. its prob like any N/A motor. u can do heads cams. ect.....

I'm going to gasket port the heads and maybe get them milled down

Re: Looking for new upgrades!?
I wouldn't mill the heads just for the sake of gaining a hair more compression. Because if something happens and you have to mill them to correct warpage you may not be able too.

Yeah true. I'm thinking of maybe doing a cam upgrade while the motor is apart

I see you have done the exhaust but is there any gain doing the headers too?

Just outta interest, why did you remove the SC tune?

I've done; SC '91 octane toon, K&N FIPK 77, F&B 72mm TB, 3" sports cat + free flow exhaust.

As soon as I added the F&B TB it lost all top end grunt, infact, doesn't even rev past 4>4.5k anymore. Need a toon bad, thankfully I don't need to drive the Jeep daily since it may do more harm than good. Although, I feel the SC one is better than stock!

Anyhow, check out Air-Ram's site! Loads of goodies to drool over there; CNC ported heads, '08 intake +TB adapter, TBs, SCT tuning, HO cams (I believe he knows a machine shop to re-grind them too), ATI damper + U/D pullies, and all the internal stuff too (pistons, H-Beams, bolts etc.). Even upgraded trannies.

I'm getting exited now so will leave it there - go to

:cool: :thumbsup:
