[BPS]

My ABS light started coming on & off over the past month or so.

Every time its happened was while I was towing my TT w/ my gryphon set to the 87 Tow Tune.

I havent been to the dealer yet to have it checked out but I did return to stock & removed the gryphon from the truck.

I'm still going to take it to the dealer, since its still under warranty.

My real question is, how do I make sure they don't flash my PCM??

I don't even know if this is a common practice, but I don't want to deal with getting my custom tune rewritten (& Charged again)

Also what if they don't see anything wrong with the truck??

Again, What if I plug in the Gryphon again the ABS Light reappears??

Thanks Lee
