Anybody know of good computer tuners for out trucks? I have a 98 Tahoe that has the block box, Wait4me and Blackbear are the only ones I know of. BB is pricey, W4M is much more affordable, but who else is out there? Mail order tune is fine, only have bolt on stuff, nothing major. I've always heard that the factory tune is very conservative.
