- 2008 MS3 GT
After 7 years using the Hypertech tuner on my 08 MS3, I have come to the conclusion that is really does nothing significant to change the car's stock parameters. I base this on 4 Mustang Dyno runs and my own data logging.
Granted it has limited capabilities with the cold air intake choices being the only real "CHANGES" allowed. The 0-60mph limited throttle choice affects things very little. I have chosen all the various parameter changes and have charted minimal AFR differences..the car still runs rich ,11.0 or so, at WOT ( barely touches 10.8 for a millisecond) with any of the Hypertech settings vs. stock. For most of the rpm's and max boost runs the AFR is in the 12-13 range so the more appropriate 11.0:1 AFR hardly ever sees the light of day. Once again, the stock setting runs mimic what I have seen with Hypertech.
(BTW, have quite a few more posts than 10..computer crashed and had to get new username, etc.)
Never have I had anything but a carbon coated tailpipe. Gas mileage, dyno'd HP/TQ/AFR/ boost readouts are within 5% or less with testing parameters the same as far as fuel octane/ambient temp...this is using 4 different cold air intake choices. Never have I seen the HP/TQ increases that Hypertech claims. Car has under 50K miles right now and in superb mechanical shape, tested for vacuum/pressure leaks without ever showing a problem.
I don't have any axes to grind here but thought I'd share some objective data. My background is fairly solid..been dealing with turbochargers since 1972 (can you remember Crown, Turbonetics !!).
Like everything else, this is my opinion and can be taken for what it's worth or not..sure the boys in TN at HT think differently but then their paycheck is involved.
