New turbo install problems
After listening to several knowledgeable people I put together a turbo "kit" for my 2000 Miata. Got it all installed and running on stock ECU. However, When I push the accelerator down the car hesitates, stumbles like it was too lean and finally goes up to 8 psi. Pretty much undriveable unless you really baby the throttle. I'm using the stock MAF and IAT that came with car. My AFR gauge goes all over the place when this bog down situation occurs and is basically unusable/unreliable.
I was told that car would be fine up to about 8 psi with stock fuel system, injectors and ECU. My thoughts are leaning toward ECU issues. Megasquirt would be nice but expensive.
Is my assumption that you can turbo a 1.8 with boost restricted to 8 psi with stock fuel, stock ECU etc. wrong?
What suggestions would members have to resolve these issues?
Thanks

Pretty much undriveable? Well yeah that tends to happen when you try to run 8 psi of boost on the stock tune and fueling. Do you go into job interviews in a wife beater? No, you prepare beforehand with all the necessary suit/tie/watch/shoe combinations that fits the situation, why should modding cars be any different?

In this order:
- Never listen to those people again, at all, for any reason
- Stop driving the car, at all, for any reason
- Buy a standalone ECU, wideband O2 sensor, and larger fuel injectors
- Install them
- Have the car professionally tuned OR learn how to tune and tune the car
