Well, after allll this info i feel like i have a pretty good grasp on turbos etc..

when it comes to tuning.. I am a bit lost.. I have never seen any dyno comparisons and how people tune.. I wanna know .. HOW it works.. timing adjustments fuel ratios etc..

Does anyone out here self tune, do i need a dyno? wideband ?? what does it take?? what do i need?
Whats the cheapest way to self tune- and whats the BEST way to self tune??

comparisons and contrasts of piggybacks, piggybacks w/ mild tuning capabilities, stand alones, chipped ecu setups etc..

If you can answer any of the above questions I'd appreciate it and it would clear alot of things up for me!

Also would like comparisons of available tuning for OBDII people who can't convert...
