Re: map richening question
if you are only going to 13 psi, and you have the motor to blow...here is what you do.
leave your stock map on there with your current tune
for every PSI you are upping the boost, take the last TWO boost columns and up them 9% for every PSI increase. So if you are going from 11 psi to 13 psi, add 18% or multiply those numbers by 1.18.
for every PSI you are upping the boost, take out ONE degree of timing for safety in those same last two columns
the map sensor wont be able to read that high, and then OF COURSE double check with a wideband, these are just recommendations
if you want to do it RIGHT, get a GM 2 Bar or Motorola 2.5 Bar Map sensor and retune properly
