BMW N54 Stage 1 Power Package w/V3 is rated 4.9 out of 5 by 78.
Rated 5 out of 5 by from Power for days! I just bought a 335i x-drive and wanted to modify it. After some research the Cobb Accessport V3 had the best reviews and was a good foundation to build on. I was a little skeptical on the amount of power that was being claimed but was blown away when I installed it! The way the power comes on and stays on is just incredible! And this was only on the sport tune! One thing that caught me by surprise was when the tunes were being down loaded/up loaded all the warning lights and notices were going off. Not to worry they all went away once the up load was complete. I've modified a lot of vehicles but this is by far one of the best bang for the buck upgrades!

Rated 5 out of 5 by from no one can touch me 0-60 I bought v2 about 2 years ago and had a problem with it witch they fixed at no cost to me. I have a 2008.335i and run 2+ now and it's almost to much power. These guys are the best and their product is the best. I'm thinking of trading up to the new unit.

Rated 5 out of 5 by from pure excellence I have bought and installed the AP on my 2008 BMW 535i and the power gains are incredible. At first when I did the install, I immediately felt the power and after about a week the check engine light came on about a misfire which I expected. After ordering the OEM spark plugs and OEM coil packs I changed them all myself and went for the best test drive ever. Needless to say my car is definitely a sleeper because everything looks stock but when I hit that gas i'm at 60 in no time. My next upgrade will be the charge pipe. The only issue I have is the excessive wheel spins when I hit the throttle. However i'm sure changing to sports tires will help.

Rated 5 out of 5 by from NOW it is the "Ultimate Driving Machine"!!! I never could have imagined that this car had so much "hidden" power inside of it but it does!!! The V3 tuner from Cobb has made me love my BMW even more than I already have. It is a truly amazing product and it makes me look forward to driving my car more and more every day. Best money that I have spent in a long time. Thanks Cobb!!!

Rated 5 out of 5 by from Happy Boosted to you!! Truly amazing transformation of this car. The device itself is amazing, the features are very useful . The bracket that sticks to the instrument label needs are much larger footprint as it doesn't stick , but really who's not a big deal, but could easily be improved.

Rated 5 out of 5 by from The AP3 is Awesome! I've just installed the AP3 Stage 1 aggressive and I can't believe the power gains. Astonishing! I also bought the FMIC, and will have that fitted in a few days. Then will remap to Stage 1 + FMIC aggressive. That will be amazing, Will then have to go to Stage 2 with the DP's and remap. These cars with this tune completely transform. I'm use to speed as my last car was a modded E55 AMG but I'd have to say this is even better. Bring on the power!

Rated 5 out of 5 by from Stage 2+ Aggressive N54 335i I went from Stage 1 Aggressive to Stage 2+ Aggressive on my E92 yesterday. Very impressive power. I recomend this product. However, I wish there was some way to display the Accessport guages onto the Idrive screen, like the JB connect. An android app would be lovely, either hard wired or bluetooth. I would buy it straight away. I don't like having the OBD2 cable exposed running across the dash. Looks cheap like a ricer.
