just got done installing ram air mod as well as 90 maf, and the 3# pulley. Have the diablo sport chip just not installed on truck yet. would these mods make my engine light come on ???? and when i have the diablo chip programmed will it go off?

 

the chip will correct it. the 90mm maf is doing it.

Be careful about running the 90mm without a chip tuned for it the 2000 or 1999 PCM it may not have the right A/F mixture....
