Got my GRP Tuned today from Jason (Shady3031). He said it had 9 gallons on it when he had it pinched, then ran it for another gallon. I fired it up right away, had it running really rich till it warmed up. Slowly began to lean it out and this thing came alive! Weather was sunny and 90 degress, and I had the engine up to 215 at its hottest, but with smoke. I decided to try and bring the temps down by slowly richening it. And so they did, coming down to about 195. I never saw a performance decrease at all. I just got more smoke and lower temps. I am completely satisfied with this engine. It's about 90% tuned at this point and will finish tuning tomorrow. I need to get the idle/LSN dialed in so the idle is consistent.

Did i mention this thing could idle all day long!

All of this while running an OD 97.
