'06 800HO Max Comp Ratio @2000' on Pump?

[HPJUNKIE]

Believe the stk ratio is 13.25:1 & can run around home @2000' on premium w/no problems. Any experience in what it can be bumped up to & remain deto safe on premium? Any Doo tech's know if the timing gets rolled back at lower elevations? Thx...

The 2006 800HO PT is 13.5-1 and the timing does get pulled back for lower elevations...I can cut it some more...but 13.9-1 to 14-1 is about it... and your pushing your luck on GOOD 92-93 at low elevations-BJ
