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.

Re: Check PCM Tire Size - Rear Ratio

Thanks BR3W. That's what I asked for, a full dyno tune, and I called reputable speed shops, not shade tree Craigslist guys. I spent $4K and a few hundred hours of my time on this swap, so another $650 to get the most out of it is worth it to me. Right now the engine is running so-so, and the shifts are not good, and I did this swap because I wanted more.

This is not a ***** and not pointed at anyone in particular, but this issue of money is a recurrent thing for me on this list. I live in the Northeast where everything costs more, so I get it, but there have been a number of examples where people have said "I got my truck painted with 5 coats of base and 3 of clear for $500" (exaggeration intentional) or something similar, which turns out to not be true here in Blue Jersey. Just recently someone told me that an engine cover from a dealer would cost $40 and all the dealers in my area quoted twice that.

I'm not accusing anyone of lying, but I guess there are parts of this country where people will work and sell stuff for much less than they do here, or maybe these are buddy deals.

It's all good and I'm always thankful for the advice and expertise I get on this list. Thanks all for your support of the hobby. It makes it better for all of us.
