Check Engine Light Question

[H What 4.6]

Last week I installed a Mac Prochamber and Mac Cat-back on my 97 GT. The Pro-Chamber uses all o-2 sensors etc. and deletes the Cats. Yesterday my check engine light came on after about 300 miles since the installation. I believe this exhaust set-up is what has tripped the light but i would just like to know if anyone could assure me. Thanks to anyone who can help.

Yes, you are going to need MIL eliminators or a computer tune to turn off the light.

that should be why it came on.. my 97 did the same thing when i put my o/r h pipe,i bought the mil elim enaters and my light is still on, but you should get soem and try it out and you should be fine

exactly^^^ if you wanna get rid of it get a tune or a hand held programmer and upload the tune in the programmer MIL eliminators are a crap shoot in the dark some work some dont(be forewarned)
