Intake - Any gains without a remap

(1/3) > >>

Hi. Just wanted to ask if any gains would be expected with say an ITG intake without having a remap i.e. on a basically standard K03 TFSI  :smiley:

KRL:
I would imagine that you would still see some gains as the OEM cover is very restrictive.  Its difficult to gauge how much though as I have not seen any stock map cars with intakes.

Thanks for the reply.

The reason I was asking is because I have recently installed an intake and ran it for 300km before going to the dyno but it gave no power gains and actually lost a bit in the mid range. I just wanted to see if anyone else had had an intake before they got remaped and hear their experience. The guy who ran the dyno did say that the airflow was increased but the car was not taking advantage and suggested a remap. He mainly works on Jap stuff (and knows his stuff) and I only went there for the dyno but I will be going to another place I know that mainly tunes VAG cars.

Anyway here is the intake I am running, it is from ITG but a bit different from the normal TFSI setup, Andy made it up for me and I am very happy with, it just seems that there are no gains without tweaking the ECU :)





and here are my dyno plots (just a note, I have a full Milltek exhaust, so the first graph shows the difference between standard(green) and with exhaust (red). The second plot shows before and after the intake and the mid range drop is clear (even though it does feel more responsive)

KRL:
Looking at your pictures it seems the TT OEM intake is not built into the engine cover is that right?

That being the case the stock TT setup may not be as restrictive as the stock S3/GTI setup etc...

RedRobin:
I ran a Carbonio on my Mk5 GTI for a long time before a Revo remap but I also had the Milltek TBE exhaust. Gave an improved throttle response and was thought to improve torque slightly but no meaningful tests were done.

More efficient but wasted potential until a remap which will then take account of the extra air and ECU will instruct accordingly.
