I would work on the clutching. The stock clutching is just terrible. it can be made to have way better low end without a tune. problem with a tune to get any real h.p. you are going to have to cut your fuel with AV gas or race fuel.

 

Speedwerx 2.5, 91 fuel.
Fast as hell & fun!!

 

Speedwerx 2.5 also gets my vote.

 

You are loosing efficiency having your motor twisted forward like that and should really be addressed first !
Speedwerx 2.5 tune with there clutching and you wont need octane additive.
I also recommend the TRS valve .

 

What did you notice from the trs valve? I just installed one on mine.

 

Double

 

I’d start with the 25 update flash and clutching first. The 25 flash supposedly helps a bunch with low and mid throttle hp but nothing more at wot.
Thats my biggest gripe with the Boost is the lack of low end throttle response. Below half throttle is a joke with these. I drove a sled with a 91 tune and it didn’t seem any better at low throttle vs stock. Is that typical or do the tunes usually pick up a lot of lower throttle response?

Mine has gobs of low-end tug.

 

I’d update it to latest stock ecu tune and clutch it. What’s your elevation you ride at?
Maybe tune it but there are other ways to gain down low.

 

I'm at 1,000' above sea level. Clutch kit recommendations? Hoping to get my first ride of the year in this weekend. Wish I could get the 25 tune done by then but I don't think it will happen.

 

Speedwerx 2.5 seems to work well for a lot of folks on here. I run BCM tunes and like them also.
You are going to get a lot of clutching opinions on here but if you go speedwerx you can get their whole package which works.
If you want BCM setup just pm me and there are a few others on here to help you with that also.
Rick also has a kit they like.
On a side note
I think the stock exhaust is good to 7 psi and I’d run that for what you’re looking for as stated above.

 

Makes sense to make everything as efficient as possible. Can all this be done on the 19 800 as well?

 

Your MY19 Axys has a different VES system than the MY22up Matryx Boost engine. The tunes are NOT compatible.

 

I was talkin that engine alignment like he said for the trs not tunes. I have battlestorm tunes

 

You can do the alignment on pretty much any sled but the way the Matryx is done is completely different than AXYS chassis with 800. I did my 15 ProX and 16 ProS as they were poor alignment OEM also.

 

On my 23 vr1 boost I ran a Speedwerx stage 2 tune with clutching and exhaust. Sled ran great compared to stock, more power everywhere and ran perfect on pump gas.

On my 24 vr1 boost I’m currently running a Bikeman 20 horse quick spool tune in combination with exhaust and clutching. It’s much snappier and exciting to ride. The bottom end power is greatly improved and feels like there’s no lag. The exhaust is louder than the speedwerx but still tolerable.

I’d suggest either one, they both make the sled way more enjoyable to ride compared to stock.

 

The BCM sets up works great 4500 miles on mine no issues the 3 tunes are great I add octane when i want to play ,and when I am on long back pack trips with the boys just run the pump gas and no issues cant speak on other tunes never tried have had great luck with BCM

 

I’ll vote for bcm. HRSS tune was also good. But I wouldn’t even run a stock boost without some boostane . Let alone tuned. Many of the tuners are starting to recommend this now as well. They like to detonate and or de rate. Even without a light or code. Fuel quality is hit or miss at any pump .

you can carry two 32 oz bottles behind the 7s. More than enough for any amount of miles you could put on in a day

 

ran last year on a bmp 20/q20/35 tune and was pleased with the results. this year i decided to switch it all up and try the speedwerx 2/2.5/3 tunes with their ck and modded muffler. will see if i see any difference this weekend.

 

It would be cool to see a 3 set draggy results from each bmp q20 vs speedwerx 2.5

 

You running pump gas??

 

110/91 non mix.

 

Is the hose tight between turbo and air box

 

I’ll double check that tomorrow morning

 

What’s your clutch set up? And what type of traction do you have .

 

Speedwerx ck. Same kit I was running last year with zero issues.

 

Reeds?

 

Did the billet intake and new reeds beginning of last season. Has may be 100 miles on it.

 

Should be able to relearn the valves & wastegate with EZ Link, no need for dealer.

 

Honestly didn’t know that.. thanks for that info

 

What helix?

 

I’ll have to look. I forgot what the kit came with.

 

So i'm going to flash it back to oem and see if i still have any of the same issues. only thing different this year from last year is the trs valve, speedwerx modded muffler and the speedwerx tunes. checked all my tubing, and the waste gate. things are as they should be.

 

Now that I rrelizdd I missed one of your posts. Is it possible the ckutching just does t work with the new tune ? And it over shifts off the launch. Or is it a different type of bog.

 

I didn’t change it from last year.. I was running the bmp tunes with the speedwerx ck with zero issues other then over rev. Talking with speedwerx today, we both agreed that going back to oem to make sure it’s not the tune was a good starting point. They are actually wondering if the valve is working so good its building too much boost too fast creating a lean bog.

 

These work great
No bog
🤔
Glad you are making progress on it groaty 👍🏻
