thanks man. i have yet to even order the Go Tech, it is just on my wishlist i guess i should say. I know this is not rocket science. I just seem to have trouble keepin the damn thing ideling, and i see other motors just sit and idle so well and are crisp with one blip. My Mach motor would def. not do that. but, as long as it was cleaned out and at race pace, it ripped and driveability was def. there. It just wouldnt idle very well. I thought that i may just have too cold of a plug to keep the fuel lit at such slow rpm. I even adjusted the idle all the way up until the clutch engaged then backed it off just to where it wouldnt engage. I will land on it soon. I am hoping to order the Go this week and get the rebuild complete on my truck and see what happens. Thanks for the info!?!
