Default Some basic tuning questions...

Since this question pertains to my mods to my 2.0L turbo I'm posting here and not in the tuning forum where everyone is pro-tuning.

I have a full turbo back and am doing an uppipe tomorrow. With this setup I know that it is possible to tune for more power through the use of an access ECU, a UTEC, ECUTEK and so on.

How important is it that the car is tuned?

By upgrading these critical exhaust components I know I am changing the car. Is it able to properly adjust? I am not looking to get the most power the cheapest or anything. If these upgraded pipes yield more power (and they do), thats fine for now since I know for a fact that me + more power = broken car.

I dont see this discussed much, so please do.

The car with the stock ECU and your mods will adjust properly and safely. However, you will undoubtedly be leaving some (quite a bit IMO) HP on the table that can NOW be taken advantage of with ECU tuning through the various methods you listed above. You will have a "faster" car than a stock car with the stock exhaust components, but somebody with stock exhaust components and a PROPERLY tuned ECU might be faster than you.

My personal opinion is that your "physical" (ie. exhaust) mods are what allows your ECU to be tuned more aggressively. You have a nice setup, and with proper tuning, you should be able to net a nice gain in HP.
