I just recieved and flashed my Xcal 2 weeks ago. It came from Pwerks. I told them I was bone stock with just a 2.5" cold air intake. And they sent me my unit with that specific tune. But now I am picking up a turboback exhaust tomorow. 3" maxfab dp, with the 2.5" dp back mopar/borla. How much tune is there? Being it's a can tune, can I get away without sending my unit back to pwerks and still be safe??
Do you have a wideband? More then likely that generic tune is way rich so the exhaust will help lean it out. Without getting on a dyno for a tune your going to be off on power anyways.At least your heading in the right direction.
It's possible an update might benefit you. I too bought the xcal from them and they asked me to send it back when I put on a pnp'd turbo/mani. and 3" O2 for an update. How much good it will actuallly do since it's a canned tune I don't know yet. I'm not expecting to get my socks knocked off, but I definitely felt a difference in the butt dyno before flashing it back to stock.
Well, if you were running PCM controlled boost I would say yes, but with a boost controller, if you don't notice you boost pick up a pound or so with the new exhaust I would say there likely isn't going to be much power there to pick up. You tune is likely plenty rich as it is.
