Monitor afr using wideband, and make sure that your wot afr is solid and not leaner then 11.9 at WOT. start off at 50psi fuel pressure and if it's rich dial back fuel pressure until your at the desired afr not leaner then 11.9 to be safe. At idle and partial throttle your o2s should be able to compensate off of fuel trims in order to keep stoich. As far as boost if you have a boost controller you should be able to run 20lbs at least. As far as timing, you could adjust the cas to 17bdtc to take advantage, all this stuff should be done on a dyno though and in increments to monitor detonation. Or just have specialty z tune your ride off of haltech and know youre in good hands :)
