I just checked my file for a 900ss from 2 months ago where i first tested how large the error really was . The error is not as large as i first implied . See below. So it seems the error between very tight and very loose is 5-6 degrees wich ties inline with your snug/running tension vs tight at 2-3 degrees
2v cam timing test 900ssie 18/5/2009
overtight as 12 on guage set to 23/75 = 116 lobe center .
Loosen belt to zero on guage = 28/68 or 110 lc
