Do I need a computer tune when putting on normal bolt ons?
No you normally do not need a computer tune when installing normal bolt ons. That includes throttle bodies, intake tubes, K&N intake system, exhaust, ported plenums, etc. You will need a tune for the following: cams, MM airbox or any different than stock MAF, nitrous, supercharger, turbo, It would be ideal to get a tune when you do the PI intake swap, but it is not necessary. It would be ideal to get a tune when you put on the underdrive pullies to raise up the idle to keep the battery charged. If you have any other specific parts, please contact Chris and he’d be happy to answer.
