well i know that i read it over and it is a good start but, now where to go?? i don't know where to find such PCM's also intercooling? are there intercooling options for specific applications or are they pretty much a custom build type of deal? most of the stuff i'm seeing is for older gp's or for 5.3L's i'm just not seeing much that i could use for MY generation car does anyone know of anyone besides zz performance to find PCM's in this year range? also, if anyone has any advice on what specific products i could use i'm all ears! i'm just trying to get some real world advice from people who have modded these cars in the real world, thanks again!
