Jeep Grand Cherokee SRT - MMX Max Effort Cam Results

The cam upgrade is complete and with a couple thousand miles on the new setup I'm happy to share the results. The bigger cam has been trouble free in daily driving and offers a significant boost in power throughout the entire RPM range. The real surprise has been the transmission tune which firmed up the shifts and certainly added to the amazing performance results. With cooler air finally arriving here in Florida the Jeep has a best 0 - 60 mph of 3.7 seconds! Only a few tenths off the times of a stock Trackhawk. For those concerned about fuel economy (not me) I lost about 10% but that might be partially due to a heavier foot with the new upgrades.
