you mean 462 with stock trans and meth, not stock tune, correct?
No Mike it did it with a stock ECM tune If i remember right . How heavy of fuel in your tune will really decide what your gains are on W/M a heavy fuel tune will only pick up 20 hp a stock tune ( meth as the extra fuel ) will pick up a bunch . Myself i only picked up 20 dyno proven HP tested by myself .
