OK, I've seen all of the threatening posts about buying used tuners from places like eBay, and how they can be married to a vehicle already. I have to admit, in this expensive quest for more HP, it is tempting to try to save money.

Meaning that, generally speaking, you can add 18% to your RWHP number and get a rough estimate of your FWHP. Like it was said above, each vehicle is different, and the only way to test FWHP accurately i...
