As far as I know, this is the basic way to tune anything. Start with a bunch of fuel and then lean it up as desired. No way to blow anything up that way..

yeah and a boost spike puts you really rich. It works out really nice with the expanded ve table of COS3.

Wow that realy low. I'm getting 15.3 to 15.8 in all round driving on a t70 turbo 5.3 with 9.5cr. I will be upgrading to a ls1 here in month or so when the machine shop get done with the block. I'm thinking of upgrade my compression on ls1 to around 9.5 to 9.8cr. Thanks for the info.
