Don't feel too much of difference with cobb..

I installed the cobb agressive tune and don't feel too much of a difference. I'm getting around 5.0 0-60's consistently but i see people getting 4.3's easily. did i do the install wrong? what else could be the issue besides im just a bad driver

So your saying you don't feel a difference from your car being stock vs your car tuned? What mods do you have on your car?

weird.. You should feel the difference after you install stage 1 sport without any mod. I would say uninstall and install it again..

0-60 is based on driving skill and how good you can launch and other factors so keep practicing!

Highly recommend going with a protuningfreaks protune. They just released their COBB custom tuning for the N55 and its sounding very promising.

I installed Stage 1 Aggressive yesterday and it's a night and day difference. I'd make sure you actually installed the aggressive map because your car can run 5.0 0-60 stock. Go to the install menu and select current map.

I'm puzzled that you can't feel a diff with the tune. When I detune my car for service appointments, it feels slow...you should feel a diff for sure.

Can you lost what mods you have

I'm under warranty and I've got a dp. You should be fine and if something were to go wrong, just remove the dp and then bring it in.

An intake may be beneficial also since you have a tune.

Nope! Leave the intake alone!

What fuel is your engine getting? Still stock cp?

I'll explain for him: intake won't do jack for an N55.

Do you have proof of this? Because it's been proven that aftermarket intakes add power to tuned N55s and N54s. I can post dynos if you'd like.
