Where can I get some info on tuning my car? I'd like to know things like when you increase timing do you increase or decrease fuel preasure and or boost. There has to be a basic formula to start off with. Thanks Sal
 
Do you use an adjustable chip?
If so, I would set the car for as much boost as the stock setting would allow. (Low knock).
Example - FP set @ 43 line off, boost 15psi, 820 O2s, .5 knock @ WOT.
Now bump boost up to 16psi. See where O2s & knock are.
Ex. - 16 psi - 810 O2s - 1.0 knock
Bump boost up 17 psi.
Ex. - 17 psi - 750 O2s - 3.0 knock.
Now I would bump up FP 1#.
Ex. - 17 psi - 790 O2s - 1.0 knock.
The above would be a pretty good tune.
Add 1 timing
Ex - 17 psi - 780 O2s - 5.0 knock
Remove timing.
Do you get the idea?
You start off low with good numbers and you start bumping up boost or timing - add some fuel as you go up.
Some cars seem to respond better to higher timing & low boost others the reverse.
I am not expert but that is the way I would approach getting a car to being tuned.
