No a tune would be fine. What exactly will be tuned post these mods? Have dealership tune?

No never bring it to a dealership to have a tune. That will only avoid your warranty if you still have it on your car. Matter of fact, dealership doesn't know how to tune a car.

A tune doesn't necessary gain you much peak power. Its purpose is to correct your A/F ratio when you have enough breath mods on your car. It will optimized your mods and most likely gain the power under the curve and give you much better drivability. Generally speaking, when you have CAI + HFC/TP + CBE or more you will need a tune.

To me all the bolt-on mods won't significantly make your car go faster. You might FEEL it pulls harder that's all. Average people gain 25-35 whp and 15-20 torque to the wheel with CAI, HFC/TP, CBE and a tune. Not saying 50whp is impossible but you will need a good tuner with secret tricks to get you there(like Jon from Z1). Otherwise it's a hit or miss.

Like others have said, I'd ditch the header. Go with Stillen Gen III, MD ART pipes(quieter than the HFCs although they are TPs) or Fast Intentions Resonated HFCs, and Fast Intentions CBE(if power gain is your priority, but FI exhaust is loud and could have little drone) and an UpRev tune.

Good luck and have fun with mods.
