my 383 made 446/424 first tune with tfs225, 11.5cr donkey cam, fast 102/102 full exhause, after brush up it made 456/428 through an s60 m6. the cam peaked at 5800 due to valve issues which will be soon fixed. I do not think you are that far off. I guess 383's dont make much more than 347. I would guess the heads and catback are holding you back, based on what I have asked recently

I think your numbers are about right, they are at par with mine. Only differenece betwen yours and mine is that you're an automatic and I'm a M6 but I also have a 12bolt so it evens us out overall. I think the 5.3 heads of ours is our limiting factor.
