I'm trying, some parts of the mid range wont take it, the top end seems like i can go 24-25, but thats something ill play with at the track. Car is very sensitive about timing for some reason, where as superglides car was not. I even desensitized the knock sensors by about 25% and it still shows up.

Did you knock the burst knock air delta table down?

Also I found the zeroing all the coefficients out helped out a lot in maintaining a more stable afr there's a thread on hp about it.

So minor update to this thread, wound up ditching the MAF honeycomb in this instance with the LS7 maf. Did some research regarding the honeycombs and while the lower end clarity is better with the honeycomb, there is a slight overall reduction in the volume of air that can enter the intake at WOT causing a bit of a restriction regardless of how free flowing the honeycomb is compared to the stock one. The newer card style MAF's seem to be better suited to be used without honeycombs because of integrated air channeling built onto the MAF itself (see bosch example below). I wound up picking up about 4% increased fuel requirements across the board without the honeycomb which will net a little bit of a gain, but nothing I can actively measure. You can visually tell why our MAF sensors among other older styles require a honeycomb, they are straight open wire designs.

Are you looking at your maf hz in your logs? Since the majority of your time isn't at wot I'd much rather have accuracy in fueling rather than a modification that's primarily good for 60%tps and up.

Yeh, it was a negligible change in hz frequency, it went about 1-2 cells lower in the hz range without the honeycomb and I lost 1 or 2 overall, but the response across the mid range and top end is what I was looking for and that also picked up a little. Next thing on my list is going to be the vmax ported LS3 and the dynomax axle back.

oh the whistling sound this LS3 tb makes never gets old lol i had a couple people already ask if it was a 3800 SC already. Although its not nearly as pronounced as a blower car, it is loud enough to easily hear it with the window down, sounds like someone whistling loudly from the front of the car.

When you say "ours"
You are referring to the stock ls4 honey comb right? And I'm in need of another, where did you order yours from?
