anyone have any problems with the ecm computer showing code 15 with a superchip?

I pulled the ecm out of my 93 5.0 lx because it was sending code 15 rom failure, and found a superchip connected to it. Now I am wondering if it is normal for the superchip to make the computer send a code 15, or if the chip or computer is bad.
I am going to hook the computer back up minus the chip to see if the code goes away.

Thanks

i had a superchip in my car for years and then the car stated running like crap. changed everything, spent a lot of money, still no change. then when i did the heater core i took out the superchip and the car ran like new again. better mileage, a lot more power, ran great. i bet if you take out the chip the code will go away. those things get old they screw a lot of stuff up.

Base Idle Reset

I'd like to post this for all the newer mustang owners and the others like me that never took the base idle reset seriously. I've had multiple engines and various setups but never once done the base idle reset. I just replaced the lifters in my car after having one collapse. I thought the...
