Need to get my 2004 Gtp tuned. If anyone is able to let me know or point me in the right direction. Headers, pulley, intercooled, ls6 springs and 1.9 rockers..just have an intense racing PCM currently. Would be nice if there is someone in the Chicago area that could.
Pm me or call/text 6125977264.
Thanks.
