Reread his question. The answer is yes.

Yes, the handheld tuners can be unlocked so it can be used on another vehicle.

But if it were me, I wouldn't even mess with a used handheld from ebay. Too many horror stories of guys getting ripped off because the handheld is still locked, and SCT or Diablo wanting a lot of cash to unlock it, yada, yada, yada.

Don't take chances, pay once and do it right the first time with a guaranteed homerun. Find a reputable tuner that suites your needs, buy the handheld from him, and let him supply you with your tunes.

Email tunes are good as a temporary measure until you can get a proper dyno tune. Personally, I wouldn't use the canned tunes that come pre-loaded on the handheld. Too generic.

There are quite a few well respected Lightning tuners available: Sal at Powersurge Performance (PSP), Johnny Lightning at Johnny Lightning Performance (JLP), Jim at JDM, JJ at Woodbine Motorsports, Greg at Racers Edge Tuning (RET), Rick at Amazon Tuning, James at Runnin With The Devil (RWTD).

Do some checking. Do some calling. Talk to the tuner. See who you like. Ask around and see if there is a tuner local to you who has a good rep.

As for your pulley swap, I'd recommend a lower pulley swap (crank pulley) over an upper pulley swap (s/c pulley) because you'll have more belt slip with an upper pulley swap because it's smaller than the OEM pulley.

Plus, since the OEM s/c pulley is pressed on, you'll need a pulley removal tool to properly remove the pulley. Using a pulley removal tool will reduce the risk of damaging the s/c snout.

PS - A header swap at your power level will not give you a lot of performance, but it will bring a smile to your face because of the sound!
