It seems considerably faster.. I actually was just messing with a new porsche, non-turbo and had a couple of car lengths by 80mph from a stop. I would say the most noticeable difference is the lower end torque and I can definitely feel that the boost is much higher.

I certainly hope mine won't have the same issue... 535(x)i is not as popular as 335i so I haven't heard any problems yet.... not sure whether 535 uses the same fuel pump as 335... I hope not

I still like that Vishnu is not too far away to drive and get my tuning done at his shop.
The AA exhaust system is sweet!
I'm still thinking if I should pull the trigger on a 08 coupe or wait for the C63.
I'm concerned about the over heating. I just read on the e90post of one coupe owner with the oil cooler retro fit still got the limp mode.
coming from 2 cars that run hot.. I don't want to bother with IC pumps, bigger cores or cooling mods.
I love the mod potential of 2 turbos, but I can for see a warranty nightmare if something goes wrong.

And on a $50,000+ car, the loss of warranty coverage could be devastating. On the Audi engine, it was clear that they chose two small-ish turbos in order to generate quick boost (and it worked), but that meant that the turbos had maxed out at about 1.0 to 1.2 bar of pressure. To go big, you needed to replace the turbos, and give up some of the early thrust.
BMW did two sequential turbos I believe in the 335. Not sure whether the tuners are working with just one or both, but you can be assured that if you have an engine failure and BMW sees a modification, you're in deep doo.

Just an FYI. The twin turbo 335 has 1 turbo per 3 cylinders. There seems to be some confusion on that...
By the time the C63 they comes they will (or should) have the 335 all dialed in. Although the C63 is more in line with the new M3 and not the 335.

I just ordered an '08 335i sedan. I test drove one that didn't even have the sport package on it, and man it outdrove my C32 in every way except flat out acceleration (they were very close). And my C32 only has 28,000 miles on it. The main difference I saw was in the steptronic automatic....utterly smooth and rev matches with the manual downshifts.

2001 vs 2007...go figure 
if 6 years not enough for manufacturers to make a better car than I don't know what to say.
with this said I'm more impressed by my friend's new GTi the same day we test drove the 335.

Many of the original supplier's pumps are going bad. BMW has a new supplier and making good on the pumps, including mine. However, due to the back order and the change in manufacturer, there has been delays of up to eight weeks to get one. They are now showing up at dealers and replacements are easier. The good thing is that the car can still be driven and it mostly affects start ups. It is actually a better condition to have than the more than typical C32 IC pump failure that has been all too common. I had three replaced! My first one when the car was new and Mercedes had me wait more than a week to get one.
New motor is bound to have some bugs to work out. And yes it does affect some 535's. All in all, the motor is sweet and the 6 speed manual is a pleasure to drive. In a straight line, the C32 pulls more, that is until it reaches 199 degrees IA temps and shuts down! And remember, many C32 owners have had to replace their supercharger, several times. And how about those nagging idler bearings that go out. A new IC is available for the 335i and a secondary oil cooler has helped others. The bugs between the two cars are just different animals. But the comparison does show you that the C32 is still a strong contender in todays high performance competitive automobile market.
Now if they would just make a Black Edition C63 ...

I know PROcede puts the highest gains, followed by XEDE and Turbo Tuner.
But XEDE is from a well known tuner (AA), whose reputation is beyond Vishnu. Turbo Tuner seems to be the simplest and safest (lowest additional boost?
).So the jury is still out for me.... I'll keep an eye on feedbacks from actual users... plus the car is for my wife anyway. So no hurry...

Yeah, he's very local to me... but even so, the mods available out there currently are a true bolt-on. They're either piggy-back system like XEDE or PROcede, or just a wire tap like Turbo Tuner. So it would be hard to screw things up in installation on the user's side. This leaves us which one is a better product.

Turbo tuner.. just to start off.. and maybe work on a DP just to get things going.
but I do agree.. AA is a better reputation.

Ah well.. ***** happens and breaks.. It happens with all new models..
Look at all the problems with the 2002 c32! No new engines that I am aware of.. but superchargers, intercooler pumps, front suspension, tranny jerks, etc, etc..
I just sold my C32 today.. I was said to see her leave, but am happy I won't have to see my favorite SA at MB anymore!

.The car already has 20000 miles on the clock, my car was one of the test cars for their product. The only issue that my car has had is a rear light bulb malfunction, display shows light is out but all is fine.Their latest map version really screams.

I also have the AA Xede and would not trade it for anything else out there. If you look at every-body's trap speed they are all the same whether Procede or xede, with the exception of Vishnu's personal car which no one else has duplicated. .The car already has 20000 miles on the clock, my car was one of the test cars for their product.
