HyRev 7500 ECU box

How can you say time slips now? If the weather does not change, my car will run pretty close to the same numbers.

Ok. Don't take my word for it. I really couldn't care less. This is something that's been WELL documented since the late 70s. It's not a bad thing and can actually be useful. I was simply letting yall know that those boxes DO retard high RPM timing. Do with the info as you will. I don't care.
