Hi There,

I've got a predator 7145 (9r07) for my 2008 GT

As I checked my custom tune on a dyno I had the problem that there is no change in CO level at the WOT 4K-7K range between 0 (standart) and shift to 9 % lean (in steps).

The CO level still stays at around 9.5 %

Any Idea what reason that could have?

co levels?

I would not expect that to change....

The CO Level measured at the exhaust during the dyno run.

The 9,5 % CO indicating that the air/fuel ratio is to rich and you can go down to approx 5 %

5 % CO level not the air/ fuel ratio

id suggest using a wideband AFR sensor as opposed to a co monitor.

Ok Thanks

Are the guys from tuningsuperstore still suporting for custom tunes ?

yes they are.

Thanks a lot Mike
