Re: Check PCM Tire Size - Rear Ratio
When quoting tunes, keep in mind what your actually getting. Plenty of places will do a 3-pull tune, and then send you on the way with the best number they get. HP Tuners credits are $100 for GenIII. GenV costs 3x as much because you need to hard code unlock the ECM. A quick flash off an existing build (basically a canned tune) is cheaper, but isn't "built" for the car its going in, so certain quirks of a build will affect the results, and there is no trans tuning or feedback.
To have a FULL tune that actually addresses things deeper than VE scaling and emission removal, you need more than 3 pulls and an hour of a tuners time. Depending on the type of setup and goals, that can be hours on the dyno and miles on the street. This is getting logs, making changes, logging again etc. Then the tuner takes the data and builds the tune (again time depending on scope), and the car goes back on the rollers to test and finally get peak #'s. A dyno is a tool, the actual #'s are virtually irrelevant.
$5-700 is what I'd expect on a GenIII/IV car that actually needs a tune built and roller time. Boosted or crazy stuff add another 1-200.
The tunes on upgraded blower/fuel system Gen V's are getting booked $850-1250+, and take HOURS on the dyno to do properly.
