[QUOTE="Jgruggs, post: 4628309, member: 10810"] Having a stage 4 port done. Ran a base line dyno to see where my numbers are at before install so I can see exactly how much I gain from the port. The guy that ran the dyno checked my A/F and timing also just to see where they were. My timing came back at 22 to 23 degrees. This is what I was told was a "safe" tune back in 03 when I put the 2.8 pulley, Magnaflow catback with X pipe, K&N cold air kit and a SCT tune. My question is this: The guy at the dyno pull told me that wasn't a safe tune, more like a race tune. Asked if I run race gas...never have. Said he wouldn't have let me run that much timing. Now I'm getting conflicting ideas on this...the company doing the port says I should run around 23 degrees timing ...on pump gas. Where should my timing be for a 2.8 pulley...no race gas...not a D.D. and sees little track time...but I like to play on the street. What are most of you running as far as timing? Thanks in advance.
