slow rev and no power when in gear

[jdarnold1990]

Okay first and foremost my car is really slow to rev and when you put it in car and let off the clutch you could have it floored and it will sit at 500 rpms and shake real bad and stall out in neutral however it will rev up fine. already did a boost leak test, replaced the ecu with a eprom ecu double and triple checked the timing checked the cat and almost everything else. its a 1990 gs-turbo has small 16g 500cc and 2g maf and 2g manifold. im about to run this car to the scrap yard also i think its just a shitty gauge but it sits at ~10 vacuum

 

[T is for TURBO]

check your timing

the timing is dead on nipples at 12 and timing marks aligned and even timed with a light.

Did you check the turbo for shaft play, check all vac lines, check cas and connections, could it be a clutch issue?

Boost/vacuum leak.

Check your ignition and fuel as well

i've checked timing and done a boost leak test and both are good how can i check for a vacuum leak?

anyone else got some ideas that i can go over?

could it possibly be the power transistor
