2.7T - data log numbers
I had my 2.7T custom tuned (aggressive tune, 93 oct, stock configuratoin; no data logs) and later removed the pre cat and main cat (same tune). The car felt VERY strong, and logged data confirmed:
Max MAF: 250.5 g/s at 6400 rpm
Max Torque: 458.6 Nm at 3000 rpm
Max HP: 303.9 HP at 6480 rpm
Max Boost: 18.1 psi at 3000 rpm
With the cats removed, we retuned the car yesterday, but did NOT manage to get any improvements:
Max MAF: 256.8 g/s at 5760 rpm
Max Torque: 438.1 Nm at 3200 rpm
Max HP: 296.3 HP at 6920 rpm
Max Boost: 20.2 psi at 3680 rpm
The 'butt meter' confirms. Maybe a little more lively above 4k rpm, but less 'torque hammer' around 3k.
What are the numbers out there for the 2.7T (VAGcom logs)?
Giac, APR, etc for Stage 2 (? gutted pre cat and eliminated main cat, rest stock)?
Why are we not seeing improvements that I expected from the surely reduced backpressure and increased exhaust flow?
What is the next bottleneck that I an tackle without spending much?
Larger turbos have to wait until year end

VERY nice! good to see that there is quite a bit of room left on the stock motor.
LOVE your torque number (already like mine a lot).

Data logging:
Vagcom, ECUx, nefmoto logger, etc.
They are all in your ECU.
Great way to check out the effects of those 'feel good mods' (like "really hot air intake", K&N filter, "Darin Intake mod".
But also a must for fine tuning custom tunes (your tuner will tell you what and how to log).

Post results!
the more logs we have the better.
Particularly MAF, IAT, (Torque if you have).
