[QUOTE="Jimmysidecarr, post: 5516813, member: 11681"] Depending on what CAI you are coming from... the 12" JLT has so much less restriction and so much more CFM that a lean out is a very real possibility. Normally the MAF reads the additional air and the PCM requests the additional fuel... but the adaptive strategy can take several drive cycles... at least that's my understanding... That can be potentially dangerous to tight pistons It is far safer to get it right ASAP and let the adaptive strategy make minor little tweaks as it was intended. Just MHO... [/QUOTE]
