383 240z Posted April 26, 2003 Share Posted April 26, 2003 I'm renting the local dyno for a few hours and was wondering if this is the right way to use my time. 1st Set timing to a base number 2nd set rpm to lowest stable RPM 3rd set Idle for max vacuume and highest idle rpm. This will all be done before hand 4th advance timing until highest HP reading 5th go lighter with dizzy springs until pinging is noted 6th change jets primary until max HP reading 7th change jets secondary for max HP reading 8th if you have a stumble over 2000 rpm your 2ndy spring is to light (how do I tell if they are to heavy??) 9th a stumble off idle adjust accelorater pump cam and squirter until smooth curve is noted.
