I just purchased an AEM Cold air intake and also dualled the exhaust in 01 Silverado 2500HD crew cab. THe issue is that I am running a little rich with fuel. Any sugesstions???

 

The electronic engine controls can handle those two modifications without issue and if anything after those mods you would be lean not rich.

Have you by any chance installed one of them cheap +20 HP do-hickies found on Ebay?

How do you know that you are rich?

 

would it be the air temp sensor at all...? idk its prolly not its just a sugestion
