Taking a trip, Hypertech III ?
I will be driving 2000 miles and was wondering it anyone had some good shift points for the Hypertech III to get some gas mileage. I have a Radix supercharger, K&N intake and a cyclone I'm getting 12-12.5

12-12.5?!!! Damn, just be happy that your gas mileage is THAT high. I only get 10.6.
I agree, call HT customer service, very knowledgeable and friendly.
On a trip that long 1 mpg = $400-$500 in gas savings. Make the call.

Re: Taking a trip, Hypertech III ?
tattoou You most likely know this but, thought I would offer the tip to save You trouble just in case. You do not use the actual tuning from the Hypertech unless it came with Radix kit with tune You are to load.
Hypertech is fine though for making shift point adjustments etc.
Please post the info You end up using on the rest of tweaks along with any other adjustmenst that you come up with. I would appreciate the info.
Thanks and hope You get what is needed to maximize drivability.

Re: Taking a trip, Hypertech III ?
During the warmer months and driving to work on rural roads at 62 mph I actually got up to 14 mpg, when it got a little colder here in Illinois, It dropped to 12- 12.5 ? The thing I would like to change is when I'm going 62 with the cruse on and come to a slight incline it will down shift and kick in the supercharge for a few seconds the shift back to 4th.
