First 50 club
87 22re
Fresh bar referee/smog
Runs well at sea level
Sucks pondwater at altitude (was at slickrock +-8000')
Mpg drops
Runs fine just guttless, pulled code #10 starter signal.

Speed sensor circuit
Main relay
Ig switch circuit(starter)
Ig switch
Ecu( yes of course it could be)
Nothing there seems like the issue?
Fixing to meter the afm and tps but the tps is new (6k miles) just passed smog 4 days ago.

Stock afm ( no mod)
Fresh tuneup
Good air filter
Afm gate swings smoothly
Throttle body is not ugly, a little sooted up, but a little shiny inside.
Not sucking oil excessive (new build) so hard to say the rings are fully seated yet?
Plugs are pretty much evenly colored.
I wonder bout injectors. Had them flowed and cleaned for new build

The answer of course... Turbocharger!:flipoff2:

I don't know if this is the case, but could it be a bad MAP sensor that's not recording baro properly? Have you tried shutting it off at altitude and restarting to reset the baseline atmosphere reading? I know late 80s/90s GM products required this to operate at altitude if you started the engine at sea level and drove to 7000' without any off/on between.
 
I ran slickrock last fall same issues.
We drove up camped ( shut down over night x3) so I doubt that...?
Map sensor ? 22re doesn't have one me thinks. Goes to check...

An awesome fab-dude from the old site did the swap in a '89+ truck.
 
No chitt?
Stock calibration is on the lean side, plugs show the story...

When you only have 75 hp at sea level, you have basically zero at 8k feet.

Haha. I just drove my 22re on propane with 4.56 gears and 40’s in the Colorado mountains. I had to put it in 4 low just to drive over the mountains on the paved road. At 12,000 foot on the trails I had to use my 4.7’s after powering out in 2.28. V-8 automatic is happening soon.
 
Yea that's how I felt @9k+- ish
Sent a set of injectors off last week to see if it was the first set or not.
@ 105# might be a candidate for a turbo
 
What compression tester were you using? The tool store rentals are almost always 25% low
 
An antique sears unit.
I figure it is more important that they are equal (low sux tho) but I tested the gauge against my compressor ( hooked it onto the comp. Same # on it and compression gauge ) I should verify beyond that tho.
