New to tuning - where should I start? I have a comp cam 212/218 .522/.529 and 115 lsa with 2 deg advance
(113 Intake Center Line, cam advanced) ground into the cam.
The stock cam had somthing like 198/204 .500/.500 and 119.5 deg LSA
and 122 deg intake center line (cam retarded).
I also have LS6 ported heads, 2003 ZO6 valves and springs, shorty headers,
and a free flowing intake (lid etc. and the SLP MAF - I think it is 80mm or so).
Presently I am running the stock PCM unmodified and the car runs fine
(trims are slightly positive , +5...7%). The car has the manual 6-speed tranny.
The car seems to be running a bit rougher at idle etc. but not by much.
I suppose I should tune for the freer flowing engine as well as the cam -
how do I go about this systematically? I have never done this before?
Thanks,
Gert
