Tuning

Hi,

I broke my mach 427 engine in with tinfoil around the head to keep the temps up. Should I tune with the tinfoil on also or should I take it off??

+1 on taking the foil off. You had the foil on to help heat cycle the engine during break-in.

But... if you're running outside in the cold winter temps of the 20s - 30s than you may want to keep a bit of the head covered to keep the temps in the low 200s.
