Is your truck stock? Right now I have a stock eaton with a 6# lower, cone filter kit and a good tune. I've never gone up against a camaro but I've gone against SRT8 Chargers. I think driving ability has a lot to do with it because I was able to take him from a dig, but he slowly started to real me in. When I started hitting my rev limiter he was still building power. Also the weight difference is in both of those cars' favor. It can't hurt to swap the plugs and gap them correctly and change the fuel filter. If the truck is stock, get a 6lb lower pulley and a good dyno tune. You'll be pleasantly surprised from the new found power.
