Question about MAP pressure on different tunes
I have a T fitting in my map
line and one end of the T is plugged with just a little rubber cap. I noticed it blew off yesterday, and i saw about 3 more psi
in my 140 tune. I know jody modifies the map
pressures in the hot tunes but not sure how. With a hole in the map
line, why didnt the truck receive less fuel instead of more? Could i do this on a dyno for a little extra hp? Just curious.
