The baseline tune i received needed major tweaking.
Fans did not come on overheated. Speedo off neg 20mph.
I provided logs to Paul. he updated me close to drive. i tuned out the rest. Do you have a OBD II data cable.
You could download HP tuner to data log. Ask Paul for a update. If you were close i would data log. Flash on my tune. I just looked at my constants my MAF diags are enabled. I know my car ran way to lean at idle. Way to rich at 1/4 - 1/2 throttle. Before i corrected.
