Depends on what you ask for really. They could make it run more economical, push up peak bhp, or smooth out power delivery. The best compromised between all 3 is usually the standard setting that the bike comes with. So unless you've changed something like the exhaust system or air box the standard fueling will probably be fine.

No save your money.
99 R6 standard was 92bhp, with a k&n air filter, dynojet stage 1 kit, micron headers and art race can I gained 7bhp.

Trust me its not worth it.
Performance air filter, race can + headers and bigger jets ect. Couldn't notice any difference at all.

I don;t know about the jet kits but a power commander was one of the best buys I ever made for my TDM, It increased the smoothness no end the power delivery was much better afterwards. I very much doubt it added more than a couple of BHP. It's isn't all about top end power gain, Mid range torque is more important in the real world.

On a twin yea.
But on a IL4 with the engine characteristics of a 2 stroke, what's the point?

I don't think you can use a PC with a carbed bike can you?

Ah well, Its booked in on monday for the dyno, would be nice to get a smoother ride, not to smooth though as i like the way it rides,

I have an exhaust baffle in the race-fit,

Should i get it done with or with out it?

Thinking of getting my CBR dyno jet'd. As standard they have a huge flat spot (more like an abyss) around 5k.

I've fitted a Fuel slip-on, and it's far less restictive with the baffle out compared to the standard can. Worth doing?

Picked bike up from the shop yestarday after he dyno jet.
I am pleased with the results,

More bottom end power.
A LOT less jerky at low speeds.
97bhp before
99.9 after
About 2% gain in torque
Bike was over-fueling and popping on deceleration but isnt now!

Well worth £110 (138 with new plugs)
This price included carb balancing.

Was dyno jetted at Dockside superbikes, Gloucester, Gloucestershire!

Probably just the carb balance was all that was needed.

No, I balanced the carbs myself before it went in, i asked if he could do them again to get them super acurate,
