Well just installed AMS DP, ETS test pipe and a ETS catbacke, it sounds great i tell ya haha but, im using a AP stage 2 tune and i think its still running very rich. Im getting a good amount of gas smell at lights or on the highway (yes i know running no cats will do that) but its smells more than normal, im also geting a good amount of black smoke when i get on it. I am as well getting my rear of the car covered in black carbon specs. Should i just pony up and get a dyno tune? Need some help here on this one, thx guys.

 

Also haha im finding yellow specs on the back as well, looks like its burning the paint?
