That sucks. You gotta have something badly out of whack. Did they check that the RPM solenoid was triggering and enabling the boost enrichment? CIS gauge would show that immediately, I would think.

Some of these figures for CIS motors sound a tad low.

My CIS motor made 395 FWHP @ 6100, 350 ft/lbs @ 5700 RPM on Bob Watson's dyno. That's 330 RWHP with RoW 3.3, 8:1 C/R, Camgrinder SC cams, factory wastegate with stock spring reads @ 12.5 PSI on the mech gauge. GHL's. Kokeln, K27/HF, dump pipe, factory RoW muffler. Stock ignition, CIS & fuel head, adjustable WUR.

Yours should make more than that. Very comfortably.

Why do I think the dyno was accurate? Same motor, before it spun a bearing, made 310 FWHP (@ 5700 RPM) with the same P&C's, heads/valves - 8:1, SC cams, stock turbo, intercooler, yada yada - oh, and a 3" open pipe for an exhaust. Pretty much right around where it should be.

My spec book gives 930 system pressure as 6.0 to 6.7 bar (88-98 PSI). I think you look to be in spec for that.
'77 S with '78 930 power and a few other things.
