Hello there
I have here at my shop a '14 Gran Cherokee SRT AWD, with the 6.4L Hemi, auto transmission.
The engine /car is pretty well maintained, they are just 30k miles old .
I'm used to tune GM platform with HPT, but I'm having trouble tuning this GPEC2 ECM, so I'd like to know if somebody here can help sending me or selling me a tune for it.
I already licenced this ECM but the HPT file I got from the "read function" to start with is a disaster.
The only engine mods are a CAI GT Momentum and performance mufflers.
The cats are still in but IDK how good they are, so the secondary O2s could be disabled.
Overhere in Brazil we have a very good pump gas called Podium rated at 98 octane , but it has anywhere from 20 to 25 percent ethanol mixed in.
I'd like to have increased power and lower engine operating temps by turning on the fan sooner.
Can one of you friends help me?
Thanks
