I need an idea of where to start on a buddy's 395 stroker i'm about to retune.. the cam is in the 240 @ .050 range.

Anyone want to take a look at the original file vs. my base file for the car to see if i'm going in the right direction?

I've changed a good deal of stuff and figured I would kind of start from stratch with the idle (RAF spreedsheets) then VE.. then MAF/WOT throttle on the dyno..

Does anyone have a good base for throttle cracker/follower tables/ideas they use for when you first start tuning.. then adjust?

Also, any ETC stuff I need to ajust besides the normal stuff? (B4349)

Any help would be really great, I haven't tuned a more radical ETC car yet.

I've got a 383 in my bird - non ETC. I found to get my idle straight, I had to take the ledge off the follower multiplier table, then apply linear smoothing from 0 to 13.55 on the air flow table. This provided a nice smooth ramp for the car to transition back to an idle state.

Does anyone want to take a look at the logs/file for this car? I did some tuning today and it idles fine and the VE is pretty safe.. but the rpm will drop like a rock when the clutch is pressed in while driving..

HELP PLEASE.. lol
