So i've had my mustang for 2 months now (2005 V6 5speed) and i've ordered my first mods. I've ordered the accel performance coil pack, new wires, and the k&n drop in filter. Now im fairly skeptical on the filter increasing hp/tq so once i get it i'd be interested in seeing some before / after results. I know nothing about dyno's. How much would it cost for me to get testing done? And where should i look to get it done? Are the iphone apps that connect to your obd via bluetooth dongle at all acurate for determining 1/4mi, 0-60, or hp/tq?

dyno testing around here is from $50-125 for 3 runs. And no the Iphone apps arnt accurate as far as HP numbers, only a dyno will be accurate.

Even if the K/N showed zero hp gains it's worth it to have once since you don't have the recurring cost of replacing a paper filter...
You will notice a difference in how your car runs with it...I'd skip the wires and coil packs, the stock stuff works just fine
Really you want to get some 3.73 rear gears, the first mod any Stang should have
