I have a 1999 silverado ecsb 4x4 with 4.8 i am wanting to order a tuned PCM from nelson but have a few questions.
From what i understand, its 300 for them to send me a tuned PCM, i dont need to send them my original PCM, is this correct? If so, will my VATS still work with the new PCM they send me or is it not abale to be used anymore? I have access to a tech2 at work if i can relearn the VATS with the new PCM..?
