My 99' C-5 coupe has most of the typical bolt-on mods including long-tube headers. One thing I don't have is an aftermarket throttlebody like the BBK unit. Is this a worthwhile mod and what can I expect for a horsepower increase? Thanx. :confused:
BBK TB is a piece of Crap!
Try having your stock TB ported, it's cheaper and you won't have any of the problems associated with BBK!
I can't believe there still in business, customer service is non existent.
Save your money for other mods!

Hand port with a grinder to clean up air turbulence. That and '01-'02 intake manifold would be a better choice.
BBK TB? Flat out, pay me $200 to chase you around with a baseball bat till you lose 10 pounds of body weight. You will see more of a performance increase, and save some $$$ :D
