:I took it to see what the power output was, only the find this big problem. I didnt get it tuned, im going in next week to have them look at everything. I thought it might of been my spark plugs but thos were replaced in august. Is there any way i can post my dyno results on here so you can have a look at them? im very new to this site so im not sure.
First thing I would do is pull codes. Make sure everything is working, then move to the next step. Are you sure your ECU is mapped for the size injectors you are using? Have you checked your temp sensor?
