Need more fuel. Pump it injectors?
Got my ski up and running and got it running perfect up until 8200rpms. Starts to lean out to 12.4 and higher up to around 12.8 and I let off. So injectors it fuel pump next? Running e tech 15.5 wheel, type 9 intercooler and Rd watercooled sc housing. Recently reflashed to r3.
Baseline fuel pressure is 48psi(rising rate hooked up) Increasing pressure makes no difference in AFR. Haven't had the balls to read the gauge at WOT yet. Also lean at idle, checking for vacuum leaks today, already checked rising rate lines.
If the weather is got (30+Celsius) I have no issues as I won't build enough rpm to have problems. Seeing 15-16 pounds at 8400 in cooler conditions. Just under 15 when warm.

Stock injectors? You need injectors with that setup.

you need injectors a stock fuel pump can handle up to a H1 wheel. You may ask how do i know i have build over 10 ski's with H1 wheels including all of mine that are turning 9200 to 9500 rpm and one with a 1.9 liter and all have stock fuel pumps.

one of your customers is running the 565cc with r3 reflash , how is that possible ?
i mean the R3 reflash is mapped for stock injectors
