mk5 gti tfsi tuning

[melition]

I finished up tuning my mk5 gti for the first time yesterday and just had some general questions. I have boost sitting around 20 psi, afr and timing look good and im seeing plenty of fuel with no kr.

My question is, i see these stage 2 tunes for these cars recommend various upgrades for this same boost level and yet mine is 100% stock. This isnt my first turbo vehicle and im not new to tuning so i know the car is safe in general on these levels, but is there something im missing?

Only issue i have seen so far is generally high iat after a few runs which i will upgrade intercooler for, but the car makes great power and runs better than i expected. Will i have any issues with this fsi engine at these power levels without the "recommended" supporting mods?

What you are missing is... Marketing.

U tune your own car for free, someone tune cars for living. thats why they need different stages and features to mention for extra charge.
