So, SR20DET with (really dark purple) 370cc injectors, FMIC, 255LPH fuelpump, stock fpr, GT2554R turbo, z32MAF.
This turbo runs best between 1.2/1.7bar-ish.. But I was told that the 370's don't really like it above 1.0bar.
Funny thing that happens is this:
At 1.0bar the engine runs pretty rich. Due to the fact that the mapping is a bit off. Buttt, it keeps running rich high up the rpm band at WOT. When checking the apexi multichecker, I read a max of about 85% peak on the injectors and around 10..0 to 11 on the A/F ratio (adjustable with safc). Feels really steady without any knock.
Isn't a 370 supposed to crap out over 80%? Are they actually 370's?
I would like to run at around 1.2 to 1.4 bar, and looking at the A/F ratio's, it looks like that's possible. But I didn't think the 370's would hold that. Could they be leaking or something?
I always thought leaking injectors would cause rough hot starting and rough idle (which it both doesn't do).
