What Chip Do I Have?

[BuickNewBee]

I just bought a nice '87 GN with some mods. I was wondering if anyone could please tell me more about the chip that is in the car.

All I know is what is on the chip.

PTE 50#
20 degree Street

I have 50# injectors so I think that is correct but I know nothing else. Can you please tell me who made it? what the correct boost to use with it is? what fuel presure I should use and what octane level fuel I should be using?

This is a great board thanks for the help.

That would be a Precision Turbo & Engine street chip. The chip program would have been written by Joe Lubrant but he no longer works there as he went back to his old non-car related job.

It should be run with 15-17# of boost give or take a #. As always should be the case you should run 92-94 octane, whatever the best is in your area. Watch your scan tool for knock and O2 numbers and you will be fine.

Good luck with the car.
