I'm pretty partial the the NelsonPerformance tunes by Allen(farmtruc). There are other tuners that would be local to you but most tuners do a one time only tune and you pay for a full tune every time you make a change to your engine. The benefit of the Nelson mail order tune is that he sells you a lifetime upgradable tune that all you pay for is reasonable shipping charges when you need a new tune. You're also dealing with one of the nation's top tuners. Like I said, you can find someone local that will give you a good tune if you prefer to deal with a brick and mortar company but if you can be patient and wait for a mail order tune it will be worth the money. When dealing with Nelson he sends you a tuned PCM that you can run a few days before sending him your core back. You can buy his PCM module if you prefer to keep your stock PCM for a backup.
