I suggest an open track day for you gentlemen...
Renntech did my ecu 190 hp 390 ft lbs., mileage increases, 9,400 mile so far trouble free, check my past posts for results, one of my best mods so far.

You are so funny! We need to get some ecuflash gurus in here to start dissecting the Sprinter ecu for us.
This would be THE MAN in regards to selling aftermarket rear diff locker kits for these vans.

McGaha

Yes that would be the **** if we could get some of those guys working on the Sprinter ECU....

We'd have:

Raised revlimiters
No speed limiters
Speed Density
Gear & speed dependent boost control
Flame thrower anti-lag
lots of different maps including those stupid ones that just blow soot
Idle speed control
Control over the fans
All kinds of data logging options


A MAX-LOCK rear differential for a Sprinter??? Do you think there would be any takers?

Of course.....you would be just the type to come up with an affordable 4x4 kit for these vans too.

I called them today and it's $700.00 for the kit and $200.00 for each program. You can do program #1 for more city driving, and program #2 for more highway driving. The device hold 4 programs ( your original stored program) plus three more.

The speed limiter is remover for $50.00

Thumbs up Re: Sprinter Performance Upgrades

So the Renntech is the $700 for kit and $200 for each program? ... What is exactly the kit? Is that another chip or the method to reprogram it? ...

As for a night at the track... my CTS-V likes EVO for lunch but I am sure your is a nice car there Gears

Back to the Sprinter... I looked at Renntech and of course no specs or install info, just call 'em. Gary 32, how much trouble was the install? How do you like the extra power? What kind of improved mileage did you get?

Thanks again to all for the inputs... we might just get some performance freaks for Sprinters on here .....

Guys : be careful with any modifacation to your fuel system and its programs. Why ? more fuel pressure = more fuel into the cylinder than the vehicle was designed to contend with, in turn causing a chain of ill effects and costly repairs. Do you think a little more power is worth a blown transmission?, voided warranty, even more soot build up, and head aches. The NCV3 3.0L engine is in no means a stinky old diesel, but a very presice and expensive technological beast. So all I ask of you is to think long and hard before messing with programming and fuel pressures, but if you decide to go that route, and something bad does happen DO NOT BLAME THE VEHICLE, for ill effects of a tuner program.

Sprint guy is 100% right, your dime.

If you are determined to take these risks make an educated choice. You are asking more from every component. We have very few real life extended results posted. Someone will have a bad experience with tuning products, (possibly me), if you have one share it, others will benefit.

Livingthedream I posted my results here:
Engine Performance Upgrades (Multi-page thread 1 2 3)
Go to NCV 3 talk and find this thread, also a search will uncover more material.
Also try the tdi club website under engine performance upgrades. Performance upgrades for Sprinters are more common in Europe. Make sure the product you buy has fuel maps adjusted for your location.
I recommend lots of careful thought...

I know age is creeping up on me when I have to Google CTS-V and think that EVO is Harley's replacement for the Shovelhead...post AMF.

Having said that I am not a prude when it comes performance. I have built a couple fast cars (pre "chip" days) and I have bought a couple of fast cars and currently am in the market for one.

This is not meant to slam anyone, just to provide some balance to readers considering a Sprinter who might stumble on to this thread. I speak only of the V-6 for I know nothing of the I-5.

I live on top of the Cumberland Plateau in TN. For those that have traveled I-40 you are familiar with our 5% grades up and down, not the steepest, but still a pretty good climb. At GVW (tall 2500; see sig) I can top the hill at 83 mph (that's on the limiter). With 1500 lbs in the back I have no trouble merging out of acceleration lanes. Yes I'm at WOT and the NAG is shifting at 3800 rpm, but I pose no threat to slowing the traffic I'm merging with. For the normal non-performance driver this engine more than likely will provide all the power you will ever need. I don't tow so the issue of having an additional 5000 lbs behind me is something I don't have to deal with. At GCVW I think accelerating on inclines and merging at highway speeds would be "sporty", or challenging if you prefer, but as Carl indicated if you build additional power into it and shift at WOT at these weights your going to have drive train issues. (It's all about mass)

It sounds like you guys doing this know what you need and are smart enough to know how to drive them. To the rest this engine will probably perform quite adequately.
