Q: Can my stock / mildly modified motorcycle benefit from a Power Commander? A: Yes - even bone stock bikes will typically enjoy crisper throttle response, improved gas mileage, smoother riding throughout the entire RPM band and an overall better riding experience. See our Testimonials for actual customer feed-back. Q: How much horsepower and torque  can I expect to gain with a PCIIIUSB? A: It depends on how far from the proper air / fuel ratio your bike is to start with. We typically see a gain of at least 2-3 HP on the top end - and very often a whole lot more.  That said, we don't promote the Power Commander as a tool for gaining top-end horsepower. We do promote it as a tool for achieving the best riding experience available throughout your entire RPM range. After all,  top-end power won't get you to the finish line first if you're lacking in the low/mid-range area, where you spend most of your time riding. Check out our Dyno Tuning Results page for actual customer performance results before and after Power Commanders and custom fuel-injection maps. Q: Is there a pre-made Dynojet map available for my bike make and model and aftermarket modifications? A: Maybe... Go to our Power Commander Price List page and under your bike's model is a link to the maps offered by Dynojet. If you don't see a Dynojet map fitting your bike's description then call or e-mail us with your modifications and we'll suggest the best match.   Q: Why should I ever pay extra for a custom map from a reputable Power Commander Tuning Center? A: While the pre-made maps generally offer significantly helpful adjustments, we're here to tell you that we can improve upon them! If you plan to be in the Nashville area and are considering a custom fuel-injection map, call Konrad at (615)874-1005 to discuss the benefits. You can also check out the performance graphs on our Dyno Tuning Results page.  Q: Are you selling brand new Power Commanders - just like I'd get from Dynojet? A: Yes, these are exactly the same items that you would receive if you purchased at higher prices directly from Dynojet. Q: I heard that one run on a dyno causes the same wear to my engine as me riding 50000 miles through a merciless rattle-snake infested desert with no oil in the tank and no beer in the saddle bags. Is this true?  A: If your dyno tuner throws a cold bike up on the dyno and fires her up with a maniacal grin then opens that throttle wide and holds her that way a while to be sure and shatter your ear drums, he may do more damage than your above described desert scenario. But a good dyno technician will treat your motorcycle like he’d treat his own. Prior to 100% throttle tests, he’d inspect your bike to ensure proper fluid levels, chain / belt and tire wear, etc. Then he’d warm your bike up and ride it just like you would on the road, monitoring your bike’s performance at low & mid RPM’s before moving to the 100% throttle test. Your mechanic could then use the test results to direct your bike toward a longer, healthier life.  Q: I just spent more bucks on aftermarket performance parts for my fuel-injected bike than all of   y’all combined – yet the ole lady still kicks my butt with her stock scoot. Should I get my money back or get a new ole lady? A: You need to ride sissy a while with your lady and get that expensive ride in for a custom fuel -injection map. All those dollars on all those horsepower making parts may as well be glued to your gas tank if your fuel mixture isn’t adjusted to your aftermarket modifications.  Q: What’s the best way to gain horsepower?  A: Lose weight and go turbo. Q: What’s the highest horsepower you’ve ever had on your dyno? A: 306 from a 2005 Hayabusa equipped with a Stage 1 Hahn Turbo System, Dynojet Ignition Module & Power Commander, and a custom fuel-injection map. Our Turbo Hayabusa page  tells the whole story.   Q: How much horsepower am I guaranteed with a dyno tune? A: While a good tune will generally gain you anywhere from 2 to 10 HP on the top end, the primary benefits of proper tuning are in the low and mid range, where most riders spend the majority of their riding time. The goal should be a better riding experience, not a higher horsepower number. Q: My bike’s plenty fast. I don’t need any more horsepower – so a dyno tune won’t be any use to me, right? A: Again, the most beneficial results of dyno tuning are found in your riding range – crisper throttle response, smoother shifting transitions, decreased popping on deceleration and possibly improved gas mileage. So while you may not need additional horsepower, there are plenty of other benefits to proper tuning. Q: Are those dynos any use for carbureted bikes? A: Yes! Carbureted bikes require fuel adjustments with aftermarket modifications just like the fuel- injected models. Dyno testing can provide beneficial indicators of whether jetting, exhaust, intake or other changes are needed. Q: How many miles do I need on my new or rebuilt motor before I come in for a custom map or carb jetting? A: 1000 miles is a good point to tune your higher RPM range. But dynos are also useful for breaking in new motors as the engine receives constant cooling and avoids the stress of over-heating in traffic or at traffic lights. And you avoid the temptation of ripping her open at full throttle before she’s ready. Q: What should I look for in a dyno shop? A: Satisfied customers! Ask your riding buddies about their experiences. Word of mouth is generally honest advertising. Read our customers' actual feed-back on our Testimonials page.
