sup all hope you've had a safe and terrific holidays!
just a couple questions directed to utec owners/ tuners because i plan on purchasing one asap. 1st is there any difference in performance between a utec that was manufactured in 2002 or 2003 and one that was an '05?
2nd i plan on getting my car dynoed and tuned but i'm sure i'll want to try to make/ tune a map myself - where can i get some detailed information (i.e. some good reading) to prep myself?
much appreciated.
peace.

 

what year is your car? you need the lastest hardware revision of the utec on 04s and higher.

if you are serious about DIY tuning, get a wideband along with that utec. otherwise your tuning will be left to timing and boost adjustments only.

fwiw, i could not live without my tuner pro.

Over at WRXHackers there is a Quick Tuning Guide on how you need to think about AFRs, timing, boost, etc.
