I heard it from this cam guy who got banned here.

a mail order tune is fine for a pretty much stock vehicle. with any power adders and the like you need to get it on the dyno.

ive used brenspeed for my SCT XC2, those tuners are dirt cheap now. take advantage of it.

I tuned my truck with an SCT DCX, and it never hit the dyno. I had an internally stock Dodge 4.7, with a Paxton NOVI 2000 hung on it, pushing 13 psi, no intercooler. Headers and exhaust.

Tuned it at home, through email. My tuner is a sharp guy. He'd send me a baseline safe tune, and I would datalog it with my laptop an Innovate LC-1 wideband OT-1 datalogger. I could hook them together and datalog any sensor in the truck as a function of rpm. Spark advance, MAP, AFR, ECT, etc, etc. I'd send him the logs, he'd adjust, and send me back a tune. My truck liked to stay in closed loop at WOT until PE timed out. In reality, if I went WOT and stayed in it, I would have blown the engine before PE timed out and it fattened up.

It took 30 iterations of the tune to perfect because of a number of issues like this. But when we were done I was getting decent mileage, there were no drivability issues, and it pulled like crazy.

You can tune a supercharged vehicle from your couch.

either or

what are the advantages of track tuning? i know thats the best way to do it, i dont know why though.

I like the idea of track tuning because you are in an actual, and not simulated environment. On a dyno, the wind isn't moving over your car (sometimes they add a big fan for radiator air flow). But you aren't experiencing drag, or even the true cooling effects of the open air. Plus, you are just measuring worthless numbers.

If you go to the track and tune, you know how certain changes affect the car, and not just the power numbers. Just because the dyno shows your car is making more power doesn't mean your car is going to be faster/ quicker. People use a dyno to optimize numbers, and a track to optimize performance.

Went the junkyard this past weekend with SVT98 and Gabegt and we found an Econoline with a 5.4L engine(not sure which number what means after the E and I didn't look), and it had the larger throttlebody, but we didn't have the right tools to get it out at the time. But I would assume that any one of those Econolines with a 5.4(97 or newer), should have the right throttlebody.
