Thanks, it took a lot of frustration to get over 300RWHP! and I'm not quite done yet.

Yes, the only thing I specified in the custom tune was to disable the knock retard and 25 degrees timing 2-7K. If you don't see a difference in timing after disconnecting the knock sensors that means yours are working as they are supposed to, i.e. not pulling timing if there is no reason. MACHONETHIS did some great work convincing me that a lot of knock sensors are unreliable, and tend to be the cause of a loss of timing. With the factory tune and the knock sensors disconnected I saw about 22 degrees 1st and 2nd gear also. If you advance the timing 10% 2-4 and 4-7K on the Diablo tune, you should be able to safely pick up a couple of HP. I'll keep posting to this thread as I get more information.
