Yeah with the motor being a 4.0L with 414hp, it's pretty much tapped out.
Adding anything to seriously up the power will just make it a shitty car to drive around town.
Not Even Close Dinan made 100+rwhp, and it still comes with factory warranty.
this is just dinan, there are other well known companies out there that offers this platform with a better motor sold with factory warranty than this flashy junk.
Dinan S3,
Racing Dynamic
ACS
Hartge
Etc all cranking out shit load more power out of the same engine NA.
