2000 GMC Jimmy Hypertech 0-60 4.3L V6
New Hypetech Max Energy programmer in my 2000 GMC Jimmy SLT 2WD, 3.08 rear..
93 Octane Tune, Firmer shifts and tuned shift points, +500rpm red line, and non restricted speed governor. The increase in HP and TQ are definitely noticeable, fuel economy is about the same...(so far haven't had it on a long trip to test hwy econ). Also the trans now shifts absolutely amazing!!
