93 camaro 5.3 s475 braking into the 10s @138mph
My 93 camaro 5.3 swap 4l80e braking into the 10s ran 10.9@138mph @ bandimere speedway morrison Co, elevation 5800ft, got it dialed in to run a little better with this setup since the old tc78 gave out earlier this year, I went ahead and got the S475 billet wheel and changed the setup around, Im doing Denmah, 3rd gear mod so it helps me build boost of the line it seems to help since the week before I ran 12.6 @ 127mph without it launching on 1.5 psi of boost, with the 3rd gear it goes a little over 6psi, my question is has anyone that has done this mod experienced a drop in timing as its building boost? Cause the issue that Im having and should explain my shitty 60ft times is that timing drops really low as its trying to make boost and doesnt come back up until 20+ mph or so, I have efi live and can try and post the datalog if someone that knows can help out let me know thanks, I know once this issue is solved it should be deep into the 10s maybe lil faster since the trap speeds are pretty good.

Go ahead and post your data log. My guess is that when loading up the trans, your going into cells which you typically don't get use which have some lower timing values in them. It also might be just that your getting more boost at the line, which are using lower timing cells. Not sure if you have checked for any torque management in your tune or not.
