... or TurboLink? :winkgrin:

Basically, you can pretty much figure it out by looking at the turbo size ... there's a good guideline chart here:

I have a scanmaster and a otc scantool. I have stock injectors and turbo.

How many miles on the car?

What are the O2 readings at wide open throttle at high speed, and it 3rd gear? (i.e. perhaps at or over 70 MPH sustained)

what does the 70mph sustained O2 readings tell you about your injectors?. TIA, Joseph

I was really asking for WOT readings. Too often when I ask for that, I get a stoplight blast, which is 1st gear and tells me nothing. I want to insure its a 3rd gear reading.

Chances are very good that a stock turbo car is fine with stock injectors. Run a bottle of Techron through the system and chances are good that they are OK.
