Tuning Question

[Tin Man]

I just started tuning on a new rebuild. WOT zips to red on the knock guage. Scanmaster shows nothing (extender chip has false knock ignore for the first 3 seconds). If I ease it up to WOT I have no knock (numbers look good; 3rd gear etc.). I have not even tried launching from a stop. Is this most likely false knock? I am afraid to stay in it and see if the knock goes away quickly. Any opinions or advice is appreciated. Thanks

Do you have poly motor mounts or a torque strap? If the engine is torquing over, the down pipe could be hitting the frame or something. This is something that happened to me.

thats a good call I just put a torque strap on mine (had a small dent in my THDP) Check your pipe asap!
