    Here is a thread that I started and another inmate added some great pics and write up of his install of the Rottweiler products. I haven't had my 2007 990 on the dyno, but it sure feels like it is making the claimed extra horses.

    I maintain the best way to make your bike go faster is training and practice. And suspension.

    But, if one is a theory-type person, I'd look very closely at the Rottweiler full-system exhaust (as well as their intake). These are not slip-on cans, it's complete snout-to-tail and look awesome.

    Remember, like we said in the hot rod business:

    Speed Costs Money, How Fast Do You Want To GO?

    If I were going to spend 1K on my bike it would be with Superplush. In fact, that's exactly what I did last year. You can make your bike faster, but you can't ride it any faster with that spongy front-end:lol3

    The title of his thread is HORSEPOWER. Why do so many of you feel the need to comment on his suspension? This is unrelated to the question.

    Maybe I should comment on his gearing and the type of chain he uses?

    I second what flynride posted. I'm running it and difference is huge and dependability/ quality is great. Check out this video above though if you go with CPR filter, they invented some awesome accessories that compliment it.

    another thing to keep in mind is that dyno sheets are worthless if the runs are not on the same machine, same temp/humidity. "adjusted" numbers can be close but if you want real improvements it going to cost some $$$. If you want to make your butt dyno happy install louder exhaust and you will swear it has more power:D

    How many base pulls where made before the intake mod? You can get that much gain just by warming the bike up. I would hope the bike stock would make close to 100 hp, also get them to reprint those runs showing AFR ,s if they cant you need to find another Dyno guy. AB :D

    I had mine tuned by the same tuner and got 102 with just Akro cans on 990R.
    I told him I thought it would be more, he stated everyone he has had on the Dyno has averaged in the high 80's to low 90's. Mine started out at 96 before he started working on the mapping. And the bike is always warmed up because they do a baseline run.
    Hoping to get back for more tuning now that I went with the Rottweiler intake.:D

    Mine had the AFR down at the bottom of the sheet(he must of clipped his link short on that Dyno sheet).
    Also this tuner is at sea level. He did tell me that the tire you have on the rear will directly impact your rear wheel Hp. Big knobbie type tires will hurt your final numbers, if you care about that:lol3

    It takes more than 1 pull on the dyno to warm the bike up they should run it until they get overlapping results, also I checked there website and he only has a Dyno Jet 200 so he has no way to load control the bike, you cannot properly tune a EFI bike without a load control Dyno. AB:-)

    FYI I just had my '07 tuned by Nels at 2wheel dyno in the pacific nw

    My bike did ~90hp. The custom tune (o2s off) showed a gain of 10hp over the akro map with O2s on. The bike has Leo Vince exhaust with baffles and an itg air filter, as well as a rekluse clutch.

    The only other chart I've seen is the one in this thread which I believe was a 2010 at about 97hp (same dyno) so I expected mine to be lower due to the older less aggressive cams and engine components of the 07/08 bikes

    Nels mentioned that knobby/heavy tires put down less power on the dyno. Also, the akro map was lean at high rpm with the open air filter.

    I do think my bike has a couple of mechanical issues - lots of oil out of the breather so either a bad balancer seal or blow by the rings - tbd. I also get a little clutch slippage sometimes since adding a rekluse clutch. I'm also trying to diagnose a rhythmic thumping/knocking I can feel through the footpegs while at less than 4300rpm or so in 6th gear and going up hill (ie under load)- not sure if it's engine, clutch, or drivetrain related.

    The bike runs MUCH better with the new tune - it's worth doing if you can find a place. Improved fuel economy, smoother, and pulls to redline much better. Nels is highly recommended. Super cool guy, knows these bikes, and uses tuneecu rather than requiring spend on a power commander.

    Also, to the point of others posts, while this bike has half the hp of my s1000rr and feels kinda slow compared, in the real world on ca back roads I'm faster on the 990 because the ergos are good and the suspension is confidence inspiring over rough pavement, etc

    I'm going to head down or Rottweiler and make a sizeable donation.
    Question, do I need to buy tune ecu ; power commander or can the stock ecu be re flashed with a new map ? Does that require the orange key ? (Got my bike used and only one key w/ no orange)

    TuneECU is a free software program used with a cable (Rottweiler sells them) to remap the ecu. Power Commander is a different, and some say better, way of doing something similar.

    Neither use the orange key.
