I have also run many logs to redline with no crashing, whereas before crashes after 6k RPM were frequent. On a side note, I'm running meth now to give a little headroom on fueling.
Well, I tried E26 tonight while it was 54F ambient and was getting HPFP drop outs above 6k RPM. Lowered to E25 and no drops, but HPFP is going down to 1400psi.

I wasn’t watching boost levels, but MAF is hitting right below 44 lb/min so I’m just finding the limit of the stock HPFP.

Anyone finding the HPD6 pumps for <$500?
