oops sorry, I mis-read it!
sounds like you know what you are doing PAV just a bit of food for thought... i pretty much have a stock car... and the power delivery is second to none.. it's just been set up really well. Ignition timing advanced, fmic, boost controller, high flow cat and 3inch cat back... had a split dump pipe bu the quality wasn't the best so I put a stock dump pipe back on and it is really running perfectly.. couldn't ask for better!
Anyhow, you sound like you know what you are doing, good luck with it!
