HOG there was no tuning done at all. That was simply the result of the top end porting alone. Corey simply laid down the before porting run done 4 years earlier over the after porting run so I could see the improvement over the before porting run. Im still running stock cats and exhaust which doesn't compliment the top end port at all. Once I get the proper headers x pipe and a more free flowing exhaust system with a fantastic Corey tune I'll be curious to see what kind of numbers it will produce then. But even with stock exhaust, top end porting makes a difference either way
But back to the reason your car is only producing 300. It could be so many different things. If you haven't already, pull the codes. They will help isolate the area to focus on. Wether its a fuel problem or secondaies not working properly. O2 sensors or cats failing. Start there first.
