Just got Dinan Stage II installed
Hey Guys,
So after much research, I went to Bud's BMW and got the Stage II installed on my 535xiT. The power difference is very real, and you can feel every extra torque. The coolest thing about the upgrade is that the car feels completely stock, yet more powerful. There are no surges, no jerks, there is a tad more lag (although I think the lag was always there, just now you have more power to wait for), and it pulls like a train (literally).
I have also noticed that torque is greatly improved in the lower RPM range. from 1,500rpm you can really feel the car pulling a lot harder. Throttle response is more sensitive though; you need 10-15% throttle to get 60% power ... on the highway, you really have to watch where your foot is. When I stomp on the throttle from 2,000rpm, the torque is ubelievable, it pulls the car very hard up until ~4,000rpm very hard. After 4,000rpm (like Dinan advertised) the boost is tapered, and the car settles into its "stock" way (or maybe a little faster) of picking up speed up to the redline. What I've noticed is that there is no longer need to go beyond 6,000rpm because its sorta "dies off" or maybe it just pulls harder mid-range now, so it seems this way.
Again, the drivability is completely stock, even better now, because the car has so much torque on tap without having to hammer the throttle. No noises, vibrations, or anything like that. All my friends who have driven/ridden in it were very impressed. In fact I think I just convinced my friend to buy the 335. When I started driving the car after the upgrade, I thought Dinan messed with the speedometer settings. I was seeing readings higher than what I felt the car was doing ... and I couldn't believe the speeds I got on the highway, and how easy I got them.
I did notice that the car runs a little hotter, however Dinan assured me that the stock oil cooler is sufficient. In any case, there will be a warning light if the car is going to overheat.
In general, its a very very cool upgrade. In comparisson, if I didn't know better I would say that this car has a 5.0-5.5L V8 under the hood.
I'm impressed, and I hope everything will hold up in reliability terms (knock on wood).
Opinions welcome.

Sounds great!
How is you gas mileage - if you keep a soft right foot?
I know what it would be when you push hard on the loud peddle!
Did Dinan suggest or change any suspension parts now that you have so much power?
Enjoy!

What a cool sleeper!
I was all Dinan until I found out about the JB3 which was considerably cheaper. The warranty on the Dinan is great; I just don't want to spend $2K to get it.
Still, have you put it on a dyno? An xi like ours probably would have about 230 or so going to the wheels (correct me if I'm wrong, or exaggerating powertrain loss) but with the Dinan, I would assume it would be back up to 300 or close to it.

Did Budd's tell you how much the Stage II increased you torque and horse power? How long did they have the car for to get the job done?

Budd's BMW has given me a print out of a dyno for a 335i convertable's before and after dyno runs. I kinda lost it
so I can't scan it and put it up now, however I will do it ASAP.Dinan stage II increases HP by 84 and torque by 122ft-lbs. Believe me, they are all there. I took a long trip on the higway today, and I was in awe the way the car behaves. At 120km/h in 6th gear if you stomp on it, it accelerates quicker than it would in fifth gear, maybe even on par with 4th ... and I am not exagerating.
Overall I am very happy with the way the car drives. Before Dinan, it felt good and solid, now its simply a beast. The amount of torque is insane, and I can use every one of them with a stick tranny.
The best part is:
1) the car retains its stock drivability - which was a big issue for me
2) I still have my warranty
3) No one knows I have it, so I can kick the shit out of an unsuspecting Mustang or something similar

I don't think because we have an "xi" you lose more to the wheels than no awd cars. The only disadvantage is that our cars are heavier.

**edit, found the thread...member justdoit did it
: http://forums.e60.net/index.php?showtopic=...mp;#entry801825and I hope you mean that dinan is providing a warranty on what bmw will deny if needed by the statement you made "2) I still have my warranty"
either way, glad you are happy with your dinan flash, happy motoring
