I just finished tuning and I only touched the HSN for now. I turned it 3 hours and it was amazing what a difference it made. The temps surprisingly stayed below 210 degrees. I still have a good amount of smoke coming out of the pipe and it doesn't seem to be bogging or anything like that. I turned it then 1 more hour and the speed was blinding!! Although when I gave it full gas from the start it sort of like bogged like it was going to accelerate then the throttle shut off a bit then accelerated back again. I had good smoke and the temps stayed the same so to be safe I just set it back to 3 hours. Could it be that the LSN needs tuning now?
