if i order the cobalt addiction stg 3 kit, cai, header, and 2.5" dp, will my car run lean with the 42# injectors that come with the kit? the kit comes with a 2.7" pulley so i wanted to check on this first

 

depending on atlitude youll run lean. i cant run anyhting smaller than a 2.9 where im at otherwise its over 100% IDC. which is basically your injectors are allways open... and cant change feul flow to compensate for power demand..

 

i would just ask them to include the 60's instead of the 42's just to be safe

 

well, im in louisiana so im pretty much 0-200 above sea level. i going to keep my stock catback on, so maybe that will help me not lean as bad
