[QUOTE="BlackNDecker, post: 12400602, member: 131894"] I have not seen confirmation that the Roadrunner ECU can adjust for changing the intake....only seen this for exhaust mods. You could always buy a used intake and make a dyno run to see...but to be honest, your biggest gains from increasing airflow should come as a result of being able to add more fuel. Once you start modifying your intake and injectors then you're exceeding what the ECU can adjust for "on the fly." BTW, the dyno graph I posted above shows less than 20 rwhp gains because these were "catted" LTHs. Regardless of how well the Roadrunner ECU adjusts for the AFRs....you should be aware that you WILL have a cel. This just reflects that the AFR is outside of what FoMoCo specified in the base ECU map. [/QUOTE]
