272 degree still can run with stock ecu, but power cant squeez until max did u used adj cam pulley.
304 degree cam need used standalone

stock is 250 i think

 

[Cheross3600]

yup stock is 250..when vvt functioned, the intake valve advanced 30 of crank angle(open at 0 TDC n close at 70 ABDC) instead of std open at 30 BTDC close 40 ABDC.do search on forum 9000 n billzilla.
