Built Performance is actually the old location of Heavy Throttle. The crew was the old install crew for Heavy Throttle. The only reason for the split is Heavy Throttle is now retail only and Built is installation with some retail (through HT of course

). They are all super nice and I would recomend DIY and then take it to them for a Swap Check. They run about $300 and you can be sure not only that it runs, but that it runs RIGHT! Save money and run strong!
