XCAL2. Because Lidio has them and he's a local business here.
Yea, that makes sense! LOL!
The X-CAL-2 is my choise and the choise of most professional tuners... it has a bit more funktions it can perform and seems to go a bit deeper and be more exact...
For the showdown I don't know anybody that have switched from X-Cal to Diablo... I know a few who switched from Diablo to X-Cal and have seen two tunes... not really a fair compairson though since the re-tunes were professional custom tunes and not canned Diablo tunes... Can't remember the exact numbers now but the gains were close to 10%! First one was a CAIed GT up from ~275 to almost 300 RWHP, the other a S/C GT from 410 or so to almost 450!
