Hey guys i was wonderin if theres anyone on here runnin a Hypertech programmer on there 2003 4.3 S10...mines 4x4 but i was just wonderin if it made any noticable difference in hp and torque??? or on fuel economy??
And hey by minor bolt ons on your 02 what do you mean? Headers and a CAI?I'm running it on my 02, I've honestly never felt any difference in power with it. I do like the fact that I can change shift points and rev limiter and other changes like tire size and gear ratio if needed.
Ok thats weird but good for you!! ha And do you hav the power programmer 3 or the max energy?I got one for my 02 off ebay for $20 bucks then had it reset for $60, so for $80 total bucks I had a perfectly working programmer....It didn't make a difference at all when I first installed it, but the more I drove it & about 500 miles later it started to pick up & now it has a little more low-mid range power....cause its somewhat harder to hook up...so I guess it has to program itself over time.
I called hypertech & the guy claimed that the programmers really help the 2002 models out a lot for some reason, but the 2000, 2001, 2003 didn't do as well. Go to www.hyptertech.com & see your vehicle horsepower gains.
