Grand Cherokee custom tune
 
Hey all, I have been running a custom tune created by my local CMR tuner in NYC. Great improvement from the DS 93 tune. I still feel though that he left a lot on the table. He spent a lot of time on timing and didn't change RPM shift points etc. Does anyone know if someone like Johan let's say can review the tune and of course get paid for it if he improves it? How can I reach out to him?

Sean at hemifevertuning.com adjusted shift points with my tune. What an amazing difference!

Dizz.... Did he mess around with timing or just shift points?

Im not dizz but I am running the 89 hemifever tune. The shift points in terms of downshifts while on the throttle are much improved and happen at at a lower rpm. The shifts are also smoother and you do not have to deal with the unpredictable 2 gear downshift experienced with the stock tune.

Both...more hp, crisper shifts, instant downshifts and higher rpm shift during WOT to take full advantage of the Hemi's power. I also ran the 93 tune(I got both 89 and 93 from Sean) and did not see any noticeable difference between the two. It just flat out drives better in all aspects and now you can tell there is a Hemi in there.
