Looking for info on chips

[David Gordon]

Where do you get chips and where do they go? Also what does a chip do. I have got the boost to 15# and the car doesnt like it. It has an adjustable fuel regulater shoulf I turn up the fuel?

Stock injectors?
I have a Turbo Tweak chip for 45 shipped.
The TT chips are one of the best.
The chip goes in the computer (that I assume is located in the passenger kick panel on a TTA).
Chips do a varity of things from boost, to fueling, timing, idle.
FP should be set at 42-43 to start with and go up to 48.
You should ba able to run 15-17 psi on 93 octane if the timing is reduced.

Sounds good I think I want one. I want to keep this thing simple yet I want it to haul but. I got beat by a almost stock 96 Z-28 yesterday pretty good. I have the boost turned down to 12# or so it will try to climp to 14# but then backs off to 12#. I didnt want to turn it up without a chip unless I dont need one when I turned it up to 16# it didnt like it at all. Exactly what do chips do?
Thanks for any info on this!

Exactly what do chips do?

Contain all parameters for control of the engine. Timing, fueling, lockup of the torque converter, etc. All very important.

A little light reading...
