Guhl Tune/Derestriction

[PowerDubs_imp]

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..

Glad you like the improvement- but it's nowhere near 20hp even on a bike that didn't have fueling adjusted already.

You also won't be anywhere near 100whp on a dyno while still having a cat and stock velocity stacks. Probably closer to 90.

Just incentive to keep playing though.

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.

Plates to block secondary air?? Whats that

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

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.

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

Yup.

Secondary Air Plates... these block the excess air to the exhaust for emissions. If you do not do this you may get the popping of the exhaust as you decelerate. With the plates installed it does not pop or do anything... ever. She just runs wonderfully with all the mods.

Here are the plates I bought, see link below. But there are other posts on this and a lot cheaper ways to do it. I had to buy a lot of parts and just added this to the bundle when I ordered.

I didn't buy plates...there is no need. Just pop off the main hose and put a plug inside it and reinstall... looks stock, works the same as plates.. and is dirt cheap. I have a picture around here somewhere...

mkv24 and GoldOxide thanks for the compliments. I love this bike and it will be with me till the end, with the rest of my collection but maybe the Indian has to go I think.

Which indian model? I rode the laconia event at NH motorspeedway and indian and harley brought every 2019 model they had.. I took every single 1 on the course at least once haha I ended up liking the Chieftain Darkhorse with the 116 Big Bore stage 3 kit the most of any bike there. It felt like it was 300lbs and had alll the power

After all this discussion I decided today is the day...

Nice cheap mod that makes power up top.

Good luck!

does anubody that has had the guhl work done have a pic of their ecm im curious what mod is done on the inside, ive tuned a few personal cars with tuning software of diff types

If you have tuned cars before- I'm confused... are you asking to see the changes he makes to the software data? That's not a 'picture'... it is numbers adjusted within numerous different tables...and certainly not shared as it is intellectual property.
