"I've now emailed AFR, RHS, Lingenfelter, Patriot, and a couple others. No one else has bothered to take the time to provide as much feedback as Rick LeBlanc did for me. I guess when they realize that I'm just getting started with engine performance mods, they feel like they're wasting their time. I think your quick thorough response says a lot about your commitment to customer service. Kudos. " - Dwayne
