Youch, that really sucks. But now you can get a better driveshaft .
BTW, you should be able to "hit" the majority of your engines cells just by cruising and holding a gear then moving the throttle up and down, just do this slowely so as not to trigger power enrichment (open loop) or DECELN or DFCO (also open loop modes). Then for the rest of the cells just extrapolate from the known good cells. This is what I do all the time, and then for the high load low engine speeds that seem to get flashed by the scanner I just use trial and error. That area of the tune is all about accel enrichment.. and the high vacuum (engine braking) cells are just there for ****s and giggles. You can tune them for optimized gas milage or in Matt's 454 we went for the "Oh my G*D that thing is beastly."
