The following has nothing to do with Steve Hurst or the show as it relates to turbo regals. The show is a reality style show designed to appeal to car folks. Despite the gross inaccuracies of modifications, everyone gets their ya-ya's out by bolting on parts. So the producers cater to this and let 'em wrench for an hour's worth of entertainment.
The better premise would be to:
1. Have the hosts promote research of the vehicles to be used instead of posturing as "we already know what to do to any car you can throw at us". Reference some websites or publications so home viewers can see how real combos are decided.
2. Establish a baseline on the cars, get 'em in good tune first, then tweak them beyond this. Every bubba in the US wants to bolt on a carb, intake and headers then deem himself the owner of a fast car. Get real and show people how to do it right. If Jeg's wants to sponsor the show then throw parts at it. Until then, stop the insanity.
3. Then at the end do a recap of the mods, costs, and change in performance. You can really do some good when you give people the ability to learn to think correctly about performance.
