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.

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. Dave

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. |

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?

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. Dave

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. Dave

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.
