Have you spoken to Ryan lately?

I had him try to tune my jeep years ago and that was a failure. Tried the SCT and he couldn’t get it to work multiple times

I see. I’m thinking I’m gonna have to pay someone who knows the Jtec then…

How was the tuning? I have a sprintex on my 03 but it has been at the tuner for ages. Seems like he’s having a tough time getting it going. Any help would be appreciated.

Does anyone have good results on tuning the 2003 4.0 sport 5spd?

It was right at 15.5 radius. The speedo gear has not been changed I have to check and see if I’m off. Obviously.

Thanks bro

Ok. I was thinking about a regear. Will do this method and see. Assuming some chalk on the ds and lift the rear out of gear and spin? For what it’s worth I have 265/75/16 on a 2003 5spd 4.0 and run 2500 at 75 mph in 5th. The math seems like 4.11

I’m just curious how accurate the Grimmjeeper calculator is… I put all the info in and it’s saying that I have 4.11 gears in my 2003 jeep sport. Pretty sure that’s a gear swap for a nonrubi? Anyone have input?

I am having a metallic ticking on deceleration while in gear from around 3k-1k. Only on deceleration if I push the clutch in it goes away. If I rev it out of gear I can get it to do it very slightly when the engine is coming down. It does occur at a stop if I rev it. Any ideas? Thank you.

I was in the fucking army for 7 years….

Lurker who just picked up my first jeep. 2003 I6 5spd with 58k.
