There is no doubt that the tune (whether JB4 or MHD) is like having a hole in the gas tank compared to stock. I also would agree when things get hot it’s likely cutting power, but my fastest laptime was 3rd lap it seemed (mostly tire and my rear wind had too much angle). It was cloudy and 60’s when I ran last week so definitely not too hot but I was wfo FTW.
Have you noticed a measurable difference with the CSF radiator? Any oil cooler upgrade.
I’ve been told the best lap time improving upgrades are:
-MCS or similar track suspension (I have st XTA which PO installed) with 9k/12k spring
-at least -3 front camber (I’m at -2.5, will have more this week)
-LSD
