383 with 224/230 or similiar cams inside please...

What kpa are y'all idling at...just curious for idle tuning reasons....I don't have a data cable at the moment but I can adjust the values around it.....I believe it to be about 50-55 kpa b/c I've seen A/F ratio differences changing the VE there with my wideband. Thanks for the input!

Thanks for the info. I might be a little lower than I thought then....probably 45-50. I have the XFI grind instead of the XE grind though...little more aggressive.
