Srsly.

A lot of us who just bought bikes have been riding for a while, or are transitioning from dirt.

My dad is scared shitless of my bike.



Dave: What's he saying about "twenty horsepower" ?

Honestly, I found my bike by searching Google for "Used Motorcycles 15068" and the website for Snow Polaris came up, with the GSX-R on it without a price, I requested a quote and he called me the next day saying it was his personal bike.


Oh and he's saying that my powercommander was probably downloaded with a basic fuel map for that bike or something, being that how it's running now is fine and won't hurt the bike, but it's running very rich and he "guarantee's" there's and extra 20 horsepower that he could get out of the motor with some tuning.

I hate hearing that, I also rode dirt for many years, it means jack shit on the street, even more so on a supersport bike. They're nothing like a dirt bike.
You could argue the point that riding a moped for years would help the transitioning from one to the other...

20 horse power from the power commander is a load of crap unless your bike is running really bad to start with.

Think of it this way, lets say you have a stock civic that makes 130hp, do you really think you could get another 15-20% just by tuning alone?

Hell my bike would make damn near 240hp if that was the case.

Power commanders tend to help "smooth" the power band out, making it more usable. This is a big plus when you run an after market intake or exhaust.

My civic makes almost that much extra just from tuning. ~90HP to 134HP with a decent tune. But then again, it's got an open exhaust, and it was tuned to be an european grocery-getter.


But yeah, I know what you mean. That's the exception that makes people think they can do it in their civic/bike/moped.

Hahaha. I can argue any point. True or not.

unless you have a dyno before and after (same dyno) it's hard to say those #s are correct. Chances are the dyno was reading high, or you could have a higher powered motor from the factory.

I've seen maybe different 350Z dynos and they range from 220-280WHP fully stock #s. almost all of them range in the 230-240WHP range.

Hell I put down 373WHP on a dyno dynamics dyno and expect to see 420-430WHP on a dyno jet.

So in other words, 44hp gain on a tune even with exhaust is pretty out there.
Only cars I've seen that have made major gains from tuning is turbo cars, tuning + bumping the boost.

Yeah, tbh, I don't know if it was actually a gain. No 'before' dyno to compare it against. I keep kicking myself for that. Maybe I just lucked out to begin with. But we did do 3 passes after warmup just to make sure.

Next time I go, I'll get the graph. I have no idea what the dyno was though. Some TÜV Bosch dyno....

EDIT: Lemme clarify a bit: Straight-through exhaust, exhaust 4-2-1 header, high-flow cat, d16y8 intake manifold, cold air intake, dry-flow filter, OBD2 -> OBD1 with a tuned hondata s300.
