I totally agree and this is to get a baseline tune on the car. Once i get it decent i am going to just on a dyno and go from there. I am OBD 1 1/2 so my tuning choices are limited to one place. It is gmtuners.com. Ryan (the owner) told me to get this scan tool and get this data (i have a list of some valves he needs) and we would start there.
As for putting the FP gauge on the car... i am definently going to before i by a pump. But i know for a fact the fuel pump is old and makes a pretty loud whining noise (kinda sounds whining). Plus so far all the data i ahve collected seems to point to the fuel pump, but i will check it before i buy
