I'm tuning on a straightaway dirt road next to a christmas tree farm. The guys at the track never up keep it and take forever in between layout changes so its usually not ready for tuning which sux. Im really not a big fan of the Nova carbs they are TOO sensitive and most people don't have the time to really learn to optimally tune them because it takes time there's no shortcuts that can be taken unless someone very experienced does it for you. I prefer to do it all myself to learn the ins, outs and exceptions to the rule.
All in all I'm very close to a good tune thanks to all you guys on here, Maximo and the magical 2058 pipe. The performance is awesome and the run time cant really be beat and for sure is better than the 86 pipes. I need to gear down to 48/13 to get this 7 port to get thru its power quicker then it will be....spectacular.
