Thread: 1990 Grand Prix turbo, Max boost tune?

The srock boost is 11 PSI?
I find it hard to believe.

My car is one of the lucky ones with the bad gauge cluster. So i dont get any correct readings.

So real time tuning, i burn it then install. Then adjust tune through the OBD1 port under the dash?

Im not quite understanding that.

I will probably like the emulation because im new to this and i am assuming it will be easier because i can adjust it as i go along.

Cool, so technically, I can run it off the laptop all the time if I really wanted? (I dont want to, that would be a fun "look what I can do" type thing). lol

I did forget to ask a very important question.
Will this chip function for me?

I found the adapter, I forgot to verify which chip I need, I do not want to reflash the stock chip due to keeping a backup.
Plus, I dont think the stock chip can be reflashed even if I wanted to.
