Re: Calling all current/past durango 5.9 owners!!!
I had a 2001 durango with 5.9l, flowmaster, k&n drop in, 180 degree thermostat. I bought a hypertech programmer and it did increase performance 5-10% depending on the tune settings (e.g. 93 octane or 87 octane), so for the $200 the Hypertech cost me on ebay, it was worth it. I never did 0-60 times, I bought it for towing.
