I have a 2007 Mustang GT and this weekend i put a Pypes O/F h-pypes with Mils eliminator to avoid a possible check light but after a couple miles the light came on. So my friend made a scan on my computer and it say's that the 02 signal is too slow to receive. Also, if I run on the check light will it affect all my others parameters.

 

+1 on this...this happened to my buddy too.

He has a 2007 GT with a Mac O/R X pipe and it was running fine with the MIL sensors until he put on his JBA axle backs. Now the check engine light is on...anybody got a fix for this?

 

You need to turn off the 02s with a tuner....the mils arent getting it done for you...not the first time this has been seen.

 

As what i've seen on the board the SCT from Brenspeed the best tuner?

 

A tune will take care of that. Get a CAI and tune package or a dyno tune and you will kill two birds with one stone. You get a great increase in performace, throttle response, and also get rid of that pesky cel. But dont worry, if you dont do that stuff right away it is not going to hurt your car driving around with that on, it's basically saying "hey there is somthing wrong with you cats!!!"...but you dont have any cats so its working fine, lol.

 

Thanks
