I got a new set of cams from bates engineering for my lsj... Specs are
Intake Exhaust
Lift .459-.460 .464-.465
Duration 270 273
Dur. @ .050 207 211
now ray at bates engineering told me he got the most po0wer by retarding the exhaust 2-4 degrees and advancing the intake 2-4 degrees from the factory set points... now this will increase valve overlap, and im having a hard time getting the car to idle.... any suggestions??

have you tried messing with the overspeed underspeed tables? Idle timing? Load a log and the tune file. I may be able to help.
will do..... this is prob the hardest part of tuning... idle..... not really sure where to put the idle spark table.. i was gonna tune the VE table and then activate the MAF sensor and tune Air Density... think it will be that big a diff??

It is possible.
What vacuum does your boost gauge read? Or is it all over the place due to the surging?
Do you have cam gears? Did you pull the timing cover to time it?
If this then you may need to go to an alpha-n tune for idle and I have no idea how you would accomplish this.Originally Posted by HNRClothing

What is your idle set to? Are you sure you have the correct info (all tables, not just flow rate) for the 60's? What are the trims doing? It may be a combination of issues, and now the cams are adding to it. Also, did you or did you not use cam gears?
