Horsepower with addons?

[Luckydawg75]

Ok I have a stock GTI MKV (09) TSI, I have installed exhaust dump, front mount inter-cooler, cold air intake. I do not have any performance tunes on the ECU, hence it is stock, so what have I actually increased the horsepower to if any?

Book some dyno time and find out

x2 on the dyno time, you may have actually lost some performance with those mods.

Little if any. Power is realized through tuning.


k04 and stuff.

Modern cars are programmed to hit a power target, throwing parts at them without tuning doesn't really do anything. The computer might actually freak out and throw a code or run worse depending on what you did until you program it to take advantage of the new conditions the car is running under.

Yeah others said it best. Chances are you did not add any power. You will need a tune and then the power will be increased greatly.

^^ one of the reasons I bought this car back in 08. The gains per dollar from just the tune were awesome. Not many other cars at the time would get a 60-80hp/100tq gain from just a tune.
