Since I dropped the 31's on my shift points seem a bit messed up, on any kind of hill on road seems i am constantly having to gas it to kick down point to maintain speed or it feel sluggish.
I know there are power chips for the engine, are there any chips out there, or a way to adjust the shift points to comp for the new tires?
This is a '98 XJ with 3.5RE and 3.55's
Thanks
