need a little help with tuning ls3 headed 408

[bigfatls6]

Im working on trying to speed density tune the VE table on an ls3 headed 408 build with a loose 4000 stalled th350. part throttle cruising looks pretty close but as soon as I put a little load on it like with the brake to get some hits in certain cells it looks to lean way out and gets sluggish. The VE table looks like the values are already pretty high. the only fuel pressure guage on the car is under the hood so i can't see it while driving.
Im posting a couple of logs and tune files as I made changes.
Let me know if you guys see some thing I missed in the tune to set it up for speed density tuning the VE table. The IAT is pretty high also not sure if this could be the issue. the car has a aeromotive a1000 pump with the fuel pressure set at 58 psi and has their regulator on the rail with fast fuel rails.
The car has 10an line ran from tank to the pump and 8an from the pump to the front of the car with 6an return.
here are some specs on the set up
PRC cnc ls3 milled .030 headed 408
238/251 .615/.632 114 cam
stock ls3 intake and ls3 injectors

here is the scan configure i used and i use a NGK afx wideband

fuel pressure base seems high for an a1000 and -10/-8 line.. that pump may getting hot at that point. Is there a reason for such high pressure? Aeromotive stuff is notorious for issues at higher pressure levels in my experiences. If it its just a 408 with a cam basically i feel that could come down. I will have to get look at the logs in a bit. not on my laptop right now

PS. i have just been playing with an extremely similar set up in a friends 02 trans am. 408 iron block with LS3 heads but stock style fuel system.. similar cam. but manual trans.. let me double check what pressure its running.. its also a SD set up. ill check all the ve tables and compare.. car drives nice and pulls hard up top.. and weve just begun really throwing timing at it.

58psi isn't high fuel pressure. That is what the factory uses on fuel injected vehicles.

every thing ls based runs 58 psi fuel pressure. I ran this same fuel system on my heads and cam ls1 with out an issue at 58 psi. It was earlier in the year though with cooler temps out side.

im talking about that kind of pressure with an A1000 though..

I installed a fuel pressure gauge inside the car and fuel pressure is staying steady at 58 psi. its not droping off like I thought it would be so im pretty sure its not a fuel delivery issue. So Now im back to trying to find some thing in the tune. im wondering if I have the ls3 injector data right in the tune? I copied it from a post on here that DSTECK posted and he seems spot on on the info he usually supplies.

Dude you have too many threads going at once. The injector data is incorrect in your tune if you are running a return style system. Also it doesn't look like you have made changes to the MAF curve which is why it is leaning out. Any rpm above 2200, or whatever your tune is set to, the computer only references the MAF table and ignores the ve.
