Well, I took my truck to High Speed Performance in Mokena Illinois to have it dyno tuned and at 6000rpm producing around 335rwhp and close to 400lbs torque the drive shaft snapped in half and took out the tranny (just had it rebuilt last summer) and exhaust. It appears that the engine and supercharger are fine, but the tranny has a crack along the side and the drive shaft is in three pieces. We were surprised to see how thin GM made there aluminum drive shafts. The owner is going to see what he can do for me and I guess go from there??? I am going to give my tranny guy a call tomorrow just for the hell of it. ![Bang Head](https://www.performancetrucks.net/forums/images/smilies/LS1Tech/gr_banghead.gif)

I was stuck between a rock and a dyno tune. I couldn't use the program from magna charger and my buddy couldn't get to my truck for a month. Well, I guess better on the dyno then on the way home or on the back roads, right!? DYNO

He thinks that the clip came out of the u-joint, which broke loose at the pig and /well what else can I say. I had the drive shaft balanced with new U-joints put in last year by a place called action machine by my house. I paid around 115 for parts and labor and was told it should hold up for my application. If i remember, I think the original u-joints had some kind of blue glue holding the C-clip in???
