It's called a website. Most vendors have one. Dinan is no different.

Dinan only posts "selected" performance claims. Look at the throttle bodies and you'll see no gain specified.

StunnaM3, How'd you hear about Singh? My buddy had him tune his E60 M5 and he loves it. Jags at Singh A.S. even changed the launch control from the USA spec to European. Now the M5 launches at 4000rpm instead of 1800. I'll see if I can get any info from Jags on his E92 tune.

Well. Since we're talking about ECU tunes, I assumed the question had to to with ECU tunes. They're listed on the website.

My point is that Dinan isn't always forthcoming with critical data, like not showing any performance information about their throttle bodies.

I'm a customer of theirs, but they could do a lot better.

Hey Stunna. Have you called Singh Autosport by any chance? I just got off the phone with Jags@Singh. He gets 27 hp with the E92M3's. I asked how he gets so much compared with Dinan.
His explanation is that this ECU has 2 processors and most tuners only have the ability to modify one of them. He can do both. Since 2007 he added. Definitely worth looking into. I know my friend's M5 felt like a different car after the Singh tune.

This is my friend Jeremiah's M5 at Singh AS with the euro launch control upgrade.

Now I'm interested.

This is a bunch of bullshit. All of the major tuners discussed here access both sides of the ECU. Pencilgeek discussed this at length in another thread. 27HP is way optimistic.

I think when tuners claim 27hp more or whatever with a tune they are not talking about 27 more of peak hp but somewhere along the way they get 27hp more than the stock tune at a certain RPM but even that is probably pushing the envelope of accuracy.

Question- what did you pay for Dinan upgrades?

Hope you don't mind what did you pay for each Dinan upgrade?

I got the 3.62 diff, the dinan exhaust and ECU done last friday at Calgary BMW (that place is straight class, can't give them enough credit, great service and sales staff!)

My initial impression as I drove away was wow! The power delivery was much smoother and it pulled very very hard across the board. There is much more torque available throughout the RPM's (keep in mind I have yet to take it over 6000 RPM since I have to break in my new diff). The car no longer feels "lazy" as I sometimes perceived. Mid-range is fantastic and that needle flies around the tach very quickly now, I have to keep my eye on it to make sure I am compliant with break in. Now I really can't give a full review of just the ECU tune because I know a ton of the torque is from the diff and I can't hit the new 8600 rpm redline for another 1000km but I am glad to report you still retain the rough idle at start up which I like! The car feels like a new beast, and drives effortlessly now. I am super impressed and happy with it

The exhaust sounds great, not too loud but definitely better than stock. There is really no drone and a minimal increase in cabin noise. The black looks awesome on my AW car and is a big reason I also made this decision. I am very pleased with this exhaust and would recommend it to anyone. Just a few more mods for me and I am done, thanks again guys!

What's that supposed to mean?

They report the largest difference, not the difference peak to peak. Peak hp might be 7900 rpm on one run and 7800 on another run, but the largest difference might be at 4000 rpm. They'll report the largest difference. As a driver you want a large difference over a broad rpm range with the difference likely exceeding the difference at peak. A tuner that only focuses on peak power is misguided.

I wouldn't be surprised to see some fudging, but it's actually pretty easy to get consistent dyno runs.

You might have been asking someone else, but I'll answer indirectly. You need to deal with a dealer and get discounts for parts and installation there
AND take advantage of Dinan rebate offers when they happen. I did springs, throttle bodies and chip saving around $2000 over quoted prices for parts and installation. Those savings were spread between my local dealer and Dinan rebates. Obviously, YMMV.

For what it's worth, Dinan is probably the last choice in ECU tuning when it comes to the 335i scene. They are light years behind the Vishnu Procede Rev 2 Canbus system. In fact, I wish Vishnu would make a tune for the M3 because the Procede seems to be far more sophisticated than any of the M3 ECU tuners out there. A 335i with Dinan software and intake makes maybe 330whp, while my Procede tuned 335i with intake makes 370whp.

When your car blows up you will know why the Dinan tune makes less power.....
