Man nobody is trying to rain on your party, it's just that something doesn't add up.
1) I was surprised to see the RS do that well from a roll against an IS38, so I commented "that's one fast RS".
2) You then said it ran dead even with a K04, which doesn't make sense because the K04 would only be a bit slower than your IS38, when most K04s run even with stage 2 IS20s.
3) Then you said K04s dyno 350... But I've never seen a 350whp K04.
4) Your car is no doubt fast as fuck, but 380whp is doutbful claim because AFAIK IS38 runs 360whp without WMI and I've seen a couple run exactly 380whp with WMI. However all the Uni tunes I've seen were the most conservative compared to GIAC, APR and Eurodyne. Idk how true this is of their IS38 tunes.
Nobody said your car or K04s were slow. All these cars are faster than mine currently. Something just doesn't add up, which could even be a result of one car or the other heatsoaking.
Your car is no doubt fast, even if it's at 360whp, though I will gladly eat my words if you really do dyno 380whp. However without WMI and with your unitronic IC which is not exactly amazing for IS38, I have some doubts about 380whp.
