Thumbs up Tyler's 500 upgrade kit

Tyler just recently upgraded my HP500's and I am extremely happy with them.

What did you do to your 500's? Are they EFI's? What type of HP are you getting now? I've been thinking of doing mine as well, but sure what.

Mine are the carbed 500's. I don't have my dyno sheets with me but they were around 650 at 5800 rpm. Tyler also did a 500EFI motor for a buddy of mine and he loves it. Tyler reprogrammed his computer after all the upgrades and he says it idles nicer now than it did when it was stock.
