the headgasket is not an issue for loss of power cause it isn't near the compression chamber. which means it wouldn't be causing a loss in power.
I contacted the place about getting the files like darrel asked me to and I have yet to get a responce from them on it. I also plan to get ahold of finishline where my previous 2 dynos were done at about dynoing just my car see what the price would be and when they could do it and to get an air fuel from them while I was at it... and that will be done before I change anything on the car too.
