Frank -

Last I heard , the biggest problem you guys were having with the Stage II
was the lean condition ? Ever figure it out ?

I have been trying to figure out how Mopar Performance came up with a 4-bbl
TB without getting the same type of lean condition .

BTW - Any more word on 4-bbl intakes and SBECs for the 97+ (R/T) being
released .
If you don't know , just tell me it will be 9 months...that is what people
at Mopar Performance tell me when they don't have a clue . :)
