I guess you could say we are masking with vmax and mace insulator too  what surprised us the most is how our kr data went from the usual 3.6(93 octane) on part throttle to almost zero! Vince had to actually triple check the tune to make sure I was not running a different tune with the knock sensor desensitized. The benefit of decreasing sragnet air and distributing equal air to all 6 runners is enough to justify the purchase for me even if I see zero gain. If we can decrease kr on this engine naturally without actually desensitizing than that is better than a few extra hp anyday. The hump on top of our plenum cover is there for the same reason as to what mace's 12mm plenum spacer help in doing. If we can see some extra gains plus help with the infamous LLT knock, than that's win win for everyone. So far the throttle response is awesome! We will all soon find out how it does on the dyno

That is quite a fair effort! I dare it's the reason why the transient response/rolling starts have definitely be improved! Makes sense as to why you no longer have a dead spot
