I have driven my car a couple times in the last couple weeks and it's doing something funny under hard acceleration. It feels like it bogs down a bit then it feels like my old '97 Cobra when the IMRC plates open up. I have only put about 300 miles on her this past year and the only work it's had done is getting the rear quarter panel and rear bumper fixed. She only has 32K miles and only mods are x pipe and cat backs. Not showing any codes at drive fine otherwise. If I get on it in 1st or second from a dig it will go to redline with out feeling it. 3rd or 4th you can feel it. Not sure if I should take to dealer to have it checked out or if I should get a tune for it and see what happens. Any thoughts would be appreciated.
