Help help help

I have a 2011 mustang GT premium and I recently modded her with BBK long tubes, BBK offroad xpipes, flow master outlaws and a JLT carbon cold air. I also had the car custom dyno tuned through Big Power racing in deer park NY. Ever since the mods I have noticed my car is idling very rough and it's been stalling. I brought the car back and they adjusted the tune but with the same issues. Now the check engine light is on and the car is riding terrible. What should I do?

Whoever tuned it should fix it.

I agree but is that common with either of my mods or do you think it was the tuner who doesn't know what he is doing?

Agreed, sounds like a tune issue, they need to make it right. There are plenty of us running similar mods with zero issues

Has anyone had any dealings with Chris at Big Power Racing in Deer Park NY? I wanna know wether he is known to do good work or not, although I should had researched that before the work was done. :headslap:

I agree with the other guys. Most likely a tune issue. But you could also have a bad TPS sensor. Did this start happening right after the tune?

Yeah it was right after the tune, I don't know the code because I'm away and not with my car but the moment I get home I'm going to check the codes
