You understand that there’s allot left on the table and the boss 600 kit is only limited by the tuner who choose to run this type of power level because the stock block/head, and fuel/fueling. Obviously you’re tuner feels different but the 600 is more capable of more power if brave or on a built motor. I’m assuming that yours is some sort of hybrid? Personally a big point for me was the ballbearings of the garret, and you can use any dp and you may have to make a reducer for whatever your intake is, you may not.
It’s nice you like your kit and meth, it’s great to have more options trickling down. But to try and compare 2 different setups on two different dynos on two different days by two different tuners, who may have different goals in the end tuning, is laughable, longevity may be a bigger concern for some also, and they might run more conservative than really needed. Some others will like the boss or aprs or iroz’s. Truth is you get allot of capability on a dead nuts solid, historically reliable turbo that can take an absolute beating with the boss kit at a fairly cheap price, your hybrid is an unknown reliability wise simply because it hasn’t been around long and doesn’t really address one of the biggest faults of the oem design. For basically 200 less than you spent, assuming it was 3950 as their website says, you can buy the boss kit and the intake. If your kit makes you happy at that price great, some of us will choose the boss kit at that price point, and we have our reasons.
