Picked up The Sirio Pipe/header combo to go with this engine today. Wow, what a top end! It finally came alive somewhere around 5 min. into the main at Rev Saturday night. - it came off a bit warm though. But I dont think this will be a problem. But I do want to get to the track early next trip to figure out the tune fully. - I switched to Byrons 30% from werks - Every store around is out completely of the werks, so it looks like I'll just be switching back full time. One weird thing though. When I first got the car on the bench and running, it kept gasping like it was asking for more and more fuel. (lean on bottom...?) So I fattened it up more and more till I had backed the lsn out prob three and a half full turns... Still happening just as bad... So I turned it back almost all the way in to stock and it came back to idle better and stopped doing it. strange. I will take more time next time, and hopefully I didnt hurt the motor much at all with that tuning hiccup and the higher temp (about 260) after the main. I actually broke around 5 min. in, so that was prob a good thing. Any ideas how to reset needles and start the tuning process over?
