@DannyP thanks for the fuel pressure guidance. My pressure is way high, and you and several other folks here (in addition to the the guys at KaddieShack) have emphasized the importance of getting this corrected straight away. Do you recommend putting gasket sealant on both sides of each gasket I add, or just on top and bottom of the combined stack? (I have Permatex #2).
@Michael - in regard to the balance tube, Danny P stated it more accurately. Several, if not all, of the 'sea level' shops I spoke with (during my build, for example) downplayed it's impact, but the local pro's here at altitude absolutely swear by it. The beauty of it is that it's a simple and inexpensive addition for your mechanic to make. @majorkahuna what did the guys at Anthony's Auto Werkes in Auburn have to have to say about it?
Michael, I'll keep you posted as I get this sorted!!
