orange or chrome ecu box?

There were some problems with the Orange box in the past. I have not read anything in awhile about them.

I use a Chrome box on most all the rides. (What Adam said by the way.)

If I'm not useing the Chrome box, a MSD is used and the OE box is still in place just incase of failure. (I've had bad luck with MSD in the past so I leave the stock box in there for a quick swap back.)

You'll notice the Chrome box advantage over the Orange box when your engine is built up.
