So I just had the max dynoed at NE Dyno and I seem to have some issues. It's running lean and I'm not sure why. Last weekend I had a SSIM done which may have caused it but I'm not sure cuz I never dynoed before so what could be causing this and is that why my numbers were lower than expected? I only have a few mods including the SSIM an Injen Intake and Megan Racing catback but I was expecting more than 203-211whp. Here is the graph where do I go from here?

 

Do you have a test pipe or a cat? If you have the stock cat and used a tailsniffer, that is the cause of it.

Here's a comparison of mine when I had a cat and when I removed it.

 

So its possible that the readings are off but why so are my # so low I thought 203-205 was stock whp I know I don't have a lot of mods but does this seem right?

 

Seems right.

What tranny do you have? Looks like an auto. What gear did you dyno in & do you have the runfiles?

 

It is an auto I did 3 in drive and the other 2 in 2nd and 3rd I've got all the run files.

205-210whp is stock for a maual, auto are usually around 190whp so your not looking too bad really.
