Upgrading the factory engine connecting rods and pistons with forged versions can allow you to more safely exceed the 400 horsepower range provided that the fueling and turbocharger are similarly upgraded. Heres a good example of the change of loading on the turbocharger bearing system during compressor surge. Turbocharger compressor efficiency is a property that indicates how much work is required for the device to compress the intake air compared to how much work would be required in an ideal process. It is worth noting that because of the sensitive nature of ECU tuning and potentially expensive problems that could arise with unsafe ECU tuning, always do plenty of research before going with a small tuner without the research and development of the larger and more established companies like Unitronic, APR, and United Motorsport. You can also see that the Intake Air Temperature barely moves through the entire pull. i feel the heat behind the headlights and on top of the hood where the turbo is(which is why i considered and turbo blanket but again it doesnt make a significant difference) I was going to get a new intake to reroute the air and even do the inlet duct scoops too and if the heat still there was thinking an aftermarket hood with vents any advice i would greatly appreciate it! This page will serve as a central location for information, and links to external information, related to the air scoop for the Mk7 GTI. Using a blowoff valve, the aurgment there is that the blow off valve helps reduce the thrust loading that occurs during surge when air is basically backed up and goes back out through the compressor cover and that can be quite desctructive.

I suspect the temperature reading from the IAT sensor is being effected by the location of the sensor inside the manifold. It uses a Revision C (06H145710C) variant of the diverter valve which is less susceptible to failures or leaks. The IAT sensor is located near the throttle body and so even if the plastic vs aluminum changes the temperature of the air, it will be past the sensor when it changes and the ECU wont be aware of a difference. Even if they were to somehow determine the compressor outlet temperature from the intake air temperature, there are several other measurements from the turbocharger that are needed to estimate the compressor efficiency. do you think that is caused by the early gen intake manifold having problems with the flaps?
