Hello guys i have a jeep cherokee 2001 4.0 with 62mm throttle body hypertech programmed 91 tune injen intake and 3" tip exhaust , in my city we are like 115f im looking to relocate iat sensor(heard was great in hot weather) and im getting 12 mpg on 245/75R16 i may have lean combustion but i want to know what great mods can i do

Besides a stroker you've pretty much hit the limit

Really oh man thanks actually im thinking in relocate the iat sensor upgrade to elec fans and upgrade injectors my jeep runs well but i have the 3.55 gears and i want my jeep to shift faster cause in 1-2 top end gear im going 70 mph and i dont want to go stroker i just want to spend to much

Mine is 2001 and i dont know what injectors fit on it ive heard about 4 holes but im not pretty sure if they arr the neon ones or what years on neon ones or ford or what ford vehicles one

Neon 784's I believe
Why are you trying to go do fast?

Upgrade the rest of the exhaust, high flow main cat and muffler, larger diameter pipe. That 3" tip is doing nothing but making noise. Pair it up with a cowl intake to get nice fresh outside air, not stinky hot engine bay air. Your bored TB will really wake up once you have done these two things.

Spectre Cowl Intake, APN Header, 2.5" Exhaust, High Flow Cat, High Flow Muffler. These are the things that will make all the difference.

Not in a 2001 with mini-cats lol

Here's your new cat: http://performance-curve.com/425250.aspx

There are quite a few guys on here who run them and have no issues, so why spend twice as much on a Mag? Plus there's a 5% CF discount code (cherokeeforum)

It's an XJ, not a race car. Just in case you forgot.

adrianregla

I know is not a race car but i want it to run the beat possible , anyways y will keep the forum for any benefit i got

ZINGGG

Huh?

X2... But it is his jeep and if he wants it to be a racer more power to him. I had my 89 lifted and paying for gas sucked. Now I want my 90 to be a street jeep cause I like the better gas mileage and the looks I get from ricers
