IAfter buying a 2004 model Apten was the only one I could fine that had a tune for that new of a model. I have been running it for 6 months and after Predator came out for a 2004 I had to try it. So I puled the chip and tuned with the predator I like having control over some things like the traction control. So I'm trying to compare. the Apten was a rocket in third on I have a vert and can tell the extra weight I miss my coupe in this department I can tell the differants with a full throttle clutch drop the coupe would smoke all the way throough 2nd and try to spin the car around I had no cats on that car though and a Acculab intake witch I don't think I will ever get another one I never got the idle right. Sorry didn't mean to get in all that. Which do you think is better I haven't had a chance to really put it to work.
