Viper55

Any sponsors or anyone else knowledgeable want to let me know what performance (engine and exhaust) upgrades are available from each and what the costs are?? I found basic info on the renntech upgrades but haven't seen any costs from the other two. Considering getting G500 and am VERY interested in what is out there for performance upgrades. If there are other tuners out there offering something, let me know.

Email is uvagrad0406@yahoo.com if that's easier. Thanks in advance for any help!!
