Ok. After rereading RRRs post I see you guys are saying the same thing.
So you would leave the curve as the factory created it ? I wouldn’t have thought detonation would be a big issue with 7.8:1 compression .
Pulling that much weight with the advance coming in that quickly, it could be. It's simple to do. You can put it back it it gives you problems. So certainly it's worth trying. Just know that you may end up with detonation. It's one of those things where you're just going to have to try it and see. What size motorhome is it?
