AA tune on e90 330i review

While I was in the Orlando area for meetings, I decided to use some free time and get the car properly tuned. All I have to say is wow.

I went to PSI (Precision Sports Industries) in Winter Park, FL to get this done in house. I stopped by around 5pm on Wednesday and we downloaded my information and sent it to AA. I returned around 12:30pm the next day and 30 minutes later my car was good to go. Big shout out to PSI for excellent customer service, professionalism, and an awesome shop. If you are in their area, there is nowhere else I would recommend to go. Check them out.

Now for the good part:

On the 600 or so mile drive back to NC I had a great chance to get used to the tune. I was use to the PBX and its jerkiness. The AA tune solved every problem I had. The throttle lag is mostly gone (it could use a little more throttle response, in my opinion, but it definitely gets rid of the horrible lag). There is a noticeable difference in power in the low rpm range. the extra torque is very nice from a dead stop. the HP in the upper range is noticeable as well. its is however, not drastically different because it is so smooth. you can feel the difference but its not the kick in the pants you might expect. Simply a very nice and smooth power increase. I will be doing a back roads test later this week and see what its like in real driving, not just highway driving.

the big pluses are increased tq and hp throughout the rev range. its noticeable, but so smooth that its not jerky. the throttle lag is mostly gone. the car does sound a bit different. the engine makes a deeper growl and I think (key word think) the exhaust note is a little different.

let me know if you have any questions. I would not hesitate to get this done. For the price...its the best bang for your buck. $400 aint a bad deal at all for what you get when the pbx is only a little less than that.

Thanks to Viral at Active Autowerkes and PSI for all the help.

I currently have the pbx still installed. just turned off.

I am looking into what would happen if I put it on map 4-6 for better throttle response and no tune on. if not, when I get the chance, I am going to uninstall it and sell it.

Glad you did the AA tune Wlew. I am still happy with mine..but after a while we always want more power

You have done a lot of tuning to your car Wlew, are you going to take it to a rolling road ? You must be around 275 HP at the crank !

why not do it while school is in? that way you can show all your friends. just go on a day when you dont have early or late classes and make it happen. you can always go, get your stuff downloaded, then go back another day and get the tune. In college I always found a way to make time, even it if meant skipping class haha.

Luckily I was able to find some time off of work to get it done during the week. I wish more car shops were open on weekends.

Highly recommend it though. It makes the car totally different. I love it.

I've got other plans....mold splitters, respray front bumper, add hamann lip. BMW performance trunk lip on the way. Possible 15mm spacers in the rear.

I've been working on a custom LED angel eye setup....that's been taking a long time....and money.

I have enough speeding tickets.....don't need to be tempted to get another one hahah.

Thanks for the review. I'll be pairing the AA tune with OBX headers and straight pipes by the end of summer, should make for some decent gains.

I got the tune done a few weeks ago while I was there to flush the brake fluid. The guys at AA were great and friendly. The tune was well worth the money and the car feels much more responsive. The car now feels how it should have been when I bought it in the first place

Thanks again to Viral, Omar, and everyone at Active Autowerke

Damn I go to orlando / winter park at least once a month, I didn't know about that shop. I've got a 330i as well, and this sounds very interesting to say the least. Looks like I need to get some money together!

dont know yet, not really paid attention to that. on my drive tpo and from florida my mpg went up by 1. but I didnt get the tune to have a little better gas mileage. on the highway if it does, great. if not, doesnt matter. these things get good enough mileage as they are. could always be better but oh well.

I'm going in for AA in the upcoming month also.

As soon as they clean the streets (damn winters), I put my summer shoes and this is my first pit stop.
