what should your air to fuel ratio be in a 03 gt auto....my mods=cai,intake manifold,plenum,throttle body,udp's,intake spacer,maf,grantelli coils,dyno tune,lca's,uca's,bilstein HD shock and strut package,kenny brown strut and shock braces,front and rear sways bars,bbk shorty headers,o/r x-pipe and slp lm1's

if you didn't have these mods ,lca's,uca's,bilstein HD shock and strut package,kenny brown strut and shock braces,front and rear sways

I would say 12.7-13.0:1 at WOT.

vanquish

+1 and cruise ratio about 14.5-15.0

BOSTANG

You want it nice and straight line on 13. No fast up and down that mean you fuel pump is not right.

My dyno chart says 7.3 for min max and average air fuel ratio...idk if that right or not

Stevecooper
