Rated 5 out of 5 by from Wow! I had purchased the Accessport V3 a few months ago form my 2011 BMW 335i and have been running it on Stage 1 aggressive. I was very happy with the response and power. I just had the Cobb FMIC,Charge Pipe,Down Pipe and AFE Stage 2 intake and it has turned my 335i into a ROCKET! I'm currently running Stage 2 Aggressive +..Couldn't be happier with results!

Rated 5 out of 5 by from Get a ProTune I previously had an AP for my Mazda Speed 3 and so was familiar with the product. Initially, I got a JB4, which is good for stock engines. However, after numerous mods, I did not think I was getting the most out of them so I went with a Pro Tune from Pro Tuning Freaks (PTF). What a difference! I collected some logs using my Cobb AP and emailed them to PTF. I also told PTF which mods I had made. PTF then sent me a custom tuned map just for my car and its mods. Power delivery is smooth and the car is responsive in every gear. Best of all, the custom tune was not very expensive. I highly recommend getting a COBB AP from a place like PTF - the bundled price of the AP + a custom tune is very reasonable considering what you are getting and considering how much most people spend on mods.

Rated 5 out of 5 by from Best tuner on the market Had another tune on my car that was very inconsistent, Changed to the V3 and the smoothness and the power delivery were exceptional! Very easy to log, so easy to change maps, and the gauge display is incredible. My car gained more power with this tune over the others.

Rated 5 out of 5 by from Linear Power Delivery! Had the COBB on my car a little over a year and I am pleased! Very linear power delivery compared to another tune I had. Easy install and data logging. The ease of data logging with this platform make it easy for pro tuning! Built in gauges is also a nice feature!

Rated 5 out of 5 by from Stage 3 build Just got the Stage 3 package installed on my 2011 335i. TQ and AFR charts attached. Peak TQ is slightly over 400 from around 270. That's about a 50% bump in TQ. I can hear the turbo spool and blow off but just slightly. The exhaust note is a little louder at idle and startup but it roars when I floor the throttle. My car is AT and exhaust sound in the cabin is better in "DS" mode rather than "D" IMO. Someone I know works at a BMW dealership took my car for a spin and said that he felt it pulls at least at par with an M3, possibly more. I am running the Stage 2 aggressive map for now but will be getting a pro tune shortly as soon as I identify a good intake. This is the fastest far I have owned. Its a blast to drive now. I also own a Mazdaspeed3 with all the COBB intake hardware (more like a Stage 1+) with a custom pro tune. 2 cars with very different characteristics but super fun to drive. Installation and tuning was done by EngineLogics, an authorized COBB dealer/protuner here in Houston. I have had an extremely good experience working with Brad over there for both my speed3 and 335i.

Rated 5 out of 5 by from Great product Got this instead of the jb4 because of how easy it was to install and the ability to pro-tune. Great product, hoping for more updates in the future.

Rated 5 out of 5 by from Smooth as butter I have the access port 3 it was a breeze to install on my 335xI. The power delivery is smooth with no flat spots. I am running the 1+ sport tune so the Torque improvements are from just off idle. I get to enjoy the extra power increase every time I drive it. Its how the car should have been tuned from the factory. A side bonus is the improved fuel economy.

Rated 3 out of 5 by from Cobb tuner My purchase and my receiving of this product was great but unfortunately I'm having an issue with the display module it is turning off and on as I'm driving down the road displaying that engine is no longer on so it will power down I've checked all the connections and a reputable dealer installed the module and the tune for me if this is a problem you have seen in the past please inform me on how to fix it if I need to exchange the module I will be happy to do so thank you very much.
