LSX install, +25 LTFT
LSX install, +25 LTFT Do I need to play with the VE table to get these #'s down. This is at idle . Mods are AFR 205's, Z06 cam, Hooker LT's, Nick Williams 90 TB, LSX 90.
Yes...you have most definitely affected the VE of the engine.
Off topic slightly, but do you have any numbers from that setup (the AFRs with the LS6 cam)? And are you using the AFR-supplied valve springs?

We just finished the install around 1 in the morning last night and put in a basic tune on it and ran a quick idle scan and yes, we're running the AFR valve springs.

LOL, That's what I said. I told my friend to go with a bigger cam , but he wants to see what it will run first.

I'm just interested to hear the numbers after seeing Z06s put down 410+ with just the AFR heads.

When we hooked it back on STFT 0 to -3,but LTFT +25. I guess we're going to try a little VE tuning and see if that changes things and if that doesn't work, we'll just have to reinstall the intake.

LSX flows a lot more air, so you gotta retune your VE, and it might be a significant change, so it's nothing out of the ordinary. If you're expecting leaks, do some WOT runs and watch the O2s/WB, see if they hold still or go bonkers.
