bigblock427 i wouldnt think theres any difference between the srt-6 and the slk32. the 32 was built before the srt-6 (2002-2004) and the srt-6 uses almost every part from the slk32 with the exception of the body and some small interior parts. mechanically its almost identical. the tcu and the trans should be the same and the ecu may have different coding for power but we havent confirmed this yet. i have a 2003 slk32 and im very interested in the mod. let me know what you need from me to help
