^ What he said. Also, you may start to enccounter overheating issues the higher the compression. Which, on a daily would be a pain in the rear if your stuck in alot of traffic. Your advantage with running a mapable ecu is that you should be able to time out all the pinking etc, which on a carbed engine running a std. 16v ecu for example is a pain. I had to compromise increased timing and better top end for a smoother non pinking drive. It was never really right, but not too bad.
I seem to recall that your valver went ok. It didn't feel like much of a compromise. Thanks for the input, guys - much appreciated.
