best programmed for 99 hoe

[isenegger]

im looking to lift my hoe and change the tires from 235/75 to 33s. i know the speedo will be off but a programmed can fix that right?? my buddy has a hypertech in his 04 silverado and i wasnt a big fan. not alot of options. i want it to shift firmer to save the tranny and correct speedo. what do yall think is good? superchips and anyothers out there. thnks!!

You're gonna need a new computer tune, rather than a chip on a 99 tahoe. Check out some of the many threads on the topic. Some names to look for, in no particular order, are:
Wester's Nelson's PCM4Less EdWright Wait4Me

Happy searching!!!

well im looking for a programmer. something like diablo, superchips. something that plugs in and you remove. what works good on 96+99 obs vortecs?

Can't answer that... don't have any of them. However, based on a post by wkspeed, you will want to look at the "high-end" hand-held versions to really accomplish anything worthwhile. From what I recall, the Diablo is a good one, but the superchips is not considered "high-end."
