“I did a stage 2 Jet Chip and Lighter / Smaller Harmonic Balancer on my 03 D (4.7l, Non HEMI Durango) and noticed together a great improvement. I’m thinking of doing this again for my 05 Durango with the Jet Chip (stage 1 this time) as the MotoBlue Harmonic balancer both available at RMPoutlet.com. Everything out the door with a smaller belt is $500, and with an advertised peak HP / Tq Gain of +30 it seems very attractive. Given the HEMI’s AWD anemic RWHP (258 is what I hear) I figure this is worth a shot, espeically given both upgrades are very much bolt on’s.”
“i have no complaints . from the moment i install it i felt the difference . i do not think it has the Hp they say but it will change specialty at MID to WOT . about gas mileage i do not know . i have never look at MPG sense i got it . around town i stomp on the gas to much and on the hwy i am going to fast to.”
