So today I took my car to be dyno tuned at a local shop named Collingdale performance, and I have a few questions. The tuner there Paul used Sniper tuning to tune my vehicle on a mustang dyno and it only put down 315hp and 337tq these numbers seem a little low to me for my mods. My mods are e-303 cam, ported e-7 heads, cobra upper and lower intake manifold, 1.6rr, 70mmtb, paxton novi 1220sl with a 3.33 pulley, BBk shorty headers, mac prochamber o/r h-pipe, flowmaster 44's. He had said that the EEC code he had never seen before (D3D), and that he just tuned it with a A9L file. Also said that I have boost leaking from either the rear main seal or lower intake because it was spitting out oil. Also said that my supercharger belt was slipping and that I was only getting 7lbs of boost, but I called paxton and I used the belt that they said I should use with that size pulley. Also when driving the car home it stalled out twice and the check engine code flashed on and off a few times. I pulled the codes and got code # 55, 15, 67, 85. Did this guy not tune the car right, because it has never just stalled out before. Also he tuned my car to an air/fuel ratio of 10.6 seems a little rich to me. I always thought that 12.1-12.3 is what you wanted when tuning. All of this cost me $500.00 so now I am alittle fustrated with the whole thing. Sorry for all the questions and the rant just neede to vent to someone besides my wife who has no idea what I am talking about. Thanks, for any help you can give.
