X amount of psi means jack shit. What sized turbo?

FYI, even a VZ21 would upset a stock ecu and stock injectors.

You are not tuned, and are asking why you are running into issues.

You are literally $200 away from having a FULLY tunable setup.

BTW, key on fuel pump prime, you definitely should be getting more than 20 psi. Your pump is dying. WHen it needs charging voltage to deliver 40+, its dying.

What can I pick up for $200 to get it tuned. Isn't a p28 ecu alone $300?
Speeduino plus $45 OBD1 adapter board. Makes it plug and play. Some assembly and firmware knowledge required, or be good at listening to instructions and understanding them.

If you already have an OBD1 ecu, you are even CLOSER budget wise. New chip and burner for the basics. Emulator to tune with a USB cable. Live tuning if you make the budget a little larger.


I still do not understand people being completely clueless and thinking a stock ecu can run any sort of turbo kit. Shows how little effort they gave into basic research.


By the way, the VZ21 turbo I mention is usually used on 500-900cc engines (0.5 liter to 0.9 liter) and even a turbo that small would run like absolute dog shit and eventually kill your engine.
