I take 60% of what the computer says to get a reasonably accurate indication of how many miles I have left.

How about the hiccups in very light trailing throttle situations at lower rpms (i.e., decelerating around 2000rpm but still applying some throttle)? Gone or there still?

I put another 15 miles on it last night. It seems to be learning as the boost curve is getting pretty consistent. It did occasionally shoot up to 23-24 psi, before settling in at 21'ish.

It feels very strong though. I occasionally had problems with throttle cut before, but that hasn't happened so far.

I don't have the hiccups you described, but I'm not sure I had them before.

They lied. Nothing new.

Who lied?

at ~70 miles post update. Feels a little stronger up top but I rotated the injectors while waiting for the ECU to come back. Yes, still some jitter at part throttle steady-state/low torque request. Most apparent in 2nd gear. Cold start misfires are pretty much gone. I have the original injectors from ver.1 of the kit.

Thanks to A.W.E. for efficiently taking care of some confusion at GIAC for the socket->flash portion of the upgrade. Stellar customer care, 4+(?) years after I bought the RSK04 kit.
