ECU tune after putting on headers is just a waste of the money you spent on good headers. Headers + no tune won't remove the torque dip at all, and only add about 10 whp. Headers + GOOD tune (such as what you'd get from @
nelsmar tuning your car) and front pipe (b/c the cat in the fp is also quite restrictive... so go catless fp or a hi-flow cat fp.... there's not much difference power-wise between the two for street-driven) CAN net you more like 30-40 whp gain and NO torque dip and improved fuel economy (b/c in NA, within a certain range, leaning the afr down a little lower into the ideal range for more power also improves fuel economy), and basically overall a much smoother running and driving car.
I'm running a header back exhaust (JDL UEL headers, Namless Performance hfc/resonated fp/op single piece, and Invidia Q300 catback exhaust), and with @
nelsmar having tuned my car, I'm getting really good gas mileage for my driving style, the car runs really smoothly, and she's just overall a very pleasant car to drive. Smooth power, smooth engagement, and throttle response is nice and positive.
