I know everyone on here loves the Predator. I also know that the SCT Xcalibrator 2 is supposed to be a good one, too. Which one is better in terms of number of options, gains, etc in everyones OPINION? I need one soon, because my 3.73s are eatin up my odometer. Probably get it within the week or so.

 

you could always just get a speedcal for $100

you're only going to get like 6 or 7 extra RWHP with a tuner and you'll have to use 91+ octane.

 

Gains are going to very similar with the supplied preformance tune, options are probably greater with the XCal 2. For custom tuning there is no advantage to either. if price matters go with a SpeedCal as nanaki posted or get a used Predator.
