I would like to take time to thank David for all his work on my 94 454 Vortec project. Everything from gathering parts, to custom ecm work and harness adapters, to troubleshooting and tuning. His products, quality, and tuning abilities are top notch. I have become a better troubleshooter/problem solver and tuner because of his help and guidance and the pricing for the quality and service you get is beyond fair. Thanks again for everything.
Sean
