I'm toying with the idea of selling my Xcal3 w/ 2 ILLS tunes to get a new guitar amp. The car's the same year and drivetrain but your ECU strategy may be different. I've had the trans reflash from the dealer (that didn't resolve the issues I was having...shift solenoid pack did).
Dyno tune is ideal but ILLS and Torrie tunes have good reputations. Doubt you'd get an ILLS tune now though since he sold the LS jumped the shark to a G8.
