  1. Performance Upgrades
    I have a 2007 Dmax LBZ (classic body style) I have a tuner, 5" exhaust, drop in K&N air filter, and PPE shim kit for increased fuel rail pressure Any other cheap ideas for increases in power??? Ive read about increasing the wastegate size and Boost valves but they are only for the older year...
