[QUOTE="David Neibert, post: 14781757, member: 153422"] I keep reading how installing a Ford Racing twin 65mm TB and a JLT resonator delete intake pipe (using stock air box and MAF) doesn't require a tune. If MAF is measuring how much air is entering the motor and wide band o2s are keeping the AF ratio in line, then does adding the 2.4 blower pulley really require a tune ? I understand the benefits of getting a tune, just wondering how far you can go without changing it and screwing up the warranty. David [/QUOTE]
