No- the guhl tune does very little over the power commander alone. About 3whp, 3wtq- from ign advance.

If you don't have the power commander- the guhl tune will gain more from stock as it adds fuel.

But the biggest gain on this bike comes from a full exhaust.

I'd expect your bike- as you just described it- to put down about 90whp. Next step would be get rid of the cat. After that- modify the velocity stacks. Then ignition advance.

I'm somewhat there with my current setup, overall satisfied. Though gearing(sprockets) could probably be optimized for my riding habits

I'd dare to say the bike is at the 100HP mark or close to it with the following Engine power mods
-Guhl's flash
-Yoshimura RSCV full exhaust
-Stock air box-for now- TSR funnel mod to follow

From my understanding (power dubs hopefully will follow up)

The TSR cover will do nothing other than make it easier for water to get in when riding in the rain. Only so much air can get through the velocity stacks no matter how open the airbox is. To make real power we need to open up the velocity stacks.

Again correct me if im wrong but I believe the velocity inserts are a whole 10mm smaller when the actual throttle body size so there is quite a bit of restriction there from the factory.

I've had a second pair of stacks sitting in my garage to be honed out for a year and just haven't gotten around to that project yet myself.

This has been covered in other post but TSR made a set of velocity stacks too. I have done both the Velocity Stacks, Air Box Funnel and Yoshimura Exhaust with Gulh's Flash.

I also installed the plates to block the secondary air to the exhaust.

Powerdubs wanted me to get it on a dyno and I have called in my area and the Cities 2 ½ hours away and no one will do it. Kind of gave up calling after 5 tries.

I love the performance now just so nice and feels right now.

The TSR donut makes a tiny bit of power all the way up top. I took mine off though because I didn't like the sound it made.

My dyno numbers are with the stock intake boot, but 3 little filter vents on the left side of the airbox and the end of the air filter cut out.

Yea- the stock velocity stacks bring the diameter down to 26mm if I remember correctly instead of the 32mm the butterflies actually are.

Welp..... Got my ECU back... Plugged it in. I currently have a slip on Yoshi, snorkel delete and a Bazzaz and now the Guhl tune....

Results:

The guy with the dyno results wasn't fibbing... It's a big difference. The bike now pulls from 0 from 5th gear ( it's a 14)... I haven't dynoed but it's certainly around 100 or more.
I recommend it. Especially for $375.. For 20+hp?
It just freed up everything. Got it on the freeway.. Didn't top it out but it buried the speedo easily... Easily...

I'm loving it.. Just enough guts to call this thing a CB1100..

Sounds exhilarating. Someday you gotta post a flick burying the CB1100 speedo.

Plates to block secondary air?? Whats that

I knew TSR made actual stack inserts also but I thought they stopped making them.

When you say donut do you mean that round snorkel delete TSR makes that just holds the air filter in place?

Glad to hear it all worked out.

As you can see for yourself, you will not be disappointed Biker
