UPDATED: Graphs shown in post #29

I drove my car 2 hours north to Allentown yesterday (in Friday rush hour traffic) because of the reputation of this particular tuning shop. Shout out to evans-tuning.com. Check out their website. They have the "world's largest online dyno database".

This was done on a Dynapack, whereby the rear wheels are removed and the hubs are secured to the dynometer. Dynapacks are generally perceived as reading a bit higher, on average, than Dynojets. My tuner agreed with that assessment. Although, a vid exists on youtube proving the opposite. Whatever...My goal with this session was to see the delta between the stock car (with Dinan exhaust and cold air intake) and with the sport tuner activated, in my case in race mode (+4 psi). PA roads suck but we do get quality pump gas.

For some odd reason, partially because I'm an idiot, I can't upload the graphs. I'll try to figure it out. In the meantime, if interested, send me your email and I'll gladly forward them to you. Here are the numbers all SAE corrected:

stock: 333.4 WHP @ 6388
356.2 WTQ @ 2769

Dinan tuner: 362.0 WHP @ 6369
407.4 WTQ @ 2844

As you can see, this simple and inexpressive device is pretty badass. Gaining 30 whp and 50 wtq is substantial for a $300 boost controller.

Next stop, Stage 4....will spending $6000 be worth it? We will find out in a couple of months when I revisit the dyno.

Congrats.

30WHP peak gain is no joke. Surprised our tiny turbo is still making that much more flow at 6400rpm with tune. I am sure the quality fuel and cold IAT contribute to the result.

It makes me think Sport Tuner, targeting +4psi throughout the band, probably is making better peak power than 1544$ worth Dinantronic Stage One.

Exactly!!! Get a DP and the thing gets pretty squirmy. Needs more rubber. Nice to see the gains.

But dyno sheets or it didn't happen!!!!!

But this is the setup I have. It's serious. Good stuff.

Those are some nice results!. Although S4 is worth it, the price is the thing haha.

Im still going to test my Stage 1, and see the difference :P, that way I can actually compare S1 with the Sport Tuner. Keep in mind that with Stage 1 Dinan honors a discount on future upgrades, so there is that.

That has got to be one of the best bang for the buck deals out there, as you describe it!

I take it you get no CELs on this set-up?

And this is without a sport downpipe???

1000 miles nothing and I dont expect anything. Its PERFECT.

These engines produce so much torque down low its a perfect street car setup.

Its really fun.

Thanks to the OP for taking the time to dyno your setup.

Stage 4 was worth it to me. The traction control light blinks between 60mph and 80mph in 3rd gear. The rear squirms around at pretty much all speeds now under heavy acceleration. I really need more rubber to mitigate the added power.

Also the tech that installed it for me said he later added pipes to an m4 and said it felt like my M2 (with stage 4) felt faster, for what it's worth. Can't trust a butt dyno, but it's still impressive that you'd even be able to compare the two.

[CosmosMpower]

30 whp and 50 wtq is pretty good, I thought consensus was that these motors are pretty much maxed out?

Is it also true that the $300 sport tuner will void your BMW factory warranty if the engine lets go vs the $1500 stage 1 tuner which keeps the warranty?

Glorious. Is this all with a stock downpipe, too?

[serrated]

Yup. I'd get a catted aftermarket DP if I get confirmation that I'd benefit at all

Interested to know to. Does the ECU record higher boost etc?

Mike @ Extreme Powerhouse says the Fabspeed 200 sport DP will gain about 10 whp without a tune. This is the model that everyone says won't throw a CEL.

So, is $1100 plus install worth it? I'm debating myself.

Interesting, Mike is a Fabspeed dealer, and Fabspeed says its a 30+ hp difference between stock DP and sportcatted DP, and has posted dyno charts showing this here on this board. Wonder what Fabspeed thinks about that

I'm all but certain the 36/21 claimed increase is with a tune, probably JB4. If not though, I'm on it like white on rice and everyone else should be as well.

I have an email in to them asking.

I'll chime in here; if you're referring to Fabspeed's original thread and dyno regarding their catted sport DP, that is my car. They used it to develop the DP. The car was (and remains) stock (i.e. no tune).

Hope this helps

What kind of gas were you running? 91 or 93?

Thanks for the reminder. So...did/does it feel like more 10 hp, or more like 36?

Dude the fabspeed dp is a huge difference get a ne and the sport tune and the M2 becomes an animal

Not sure if I'm "dude" here, but my Dinan Stage 4 kit is supposed to ship in the next week or so.

I'm just interested in what the Fabspeed DP really adds...
