The closest tuner i have sells the both, but he seems to show off the Xcal charts a little more. I did the math,. here is how it works out...What would you guys do...?
OPTION #1
Predator=$250
CL racer= $269 (brenspeed)
Custom Tune= $125
---------------------------
total $644ish (doesn't include shipping)
OPTION #2
Brenspeed pkg. $599 (with 3 premade tunes, doesn't include shipping)
