A few ways
1) power to the track efficiency
2) superior track design
3) better attack angle to stay on the snow instead of trenching like a pipeliner
4) The food cooker is on the can on a cat and on the clutch cover of the doo

pretty valid points. I was gonna say because the doo is usually at a 38 degree angle but you covered it better..lol

HOLLY toledo that is going to be a squeaker. I would not do this mod. 94.3 lambda...like seriously, that is VERY LEAN. To those who don't know lambda, that is equivalent to about 13.8-13.9 afr.
I see it goes as high as 97.4 lambda, that is about 14.2 afr at 8,000rpms, guaranteed trouble to the unknowing. Too lean BAD tune setup.

Kibbels, avoid that setup is my advise. Yes it make's impressive HP but it won't for too long. I see a monoblock in the future. LOL

OK, here are some basic advise when looking for a tune or performance up grade for your sled.
People really get hung up on hp and forget some basic important aspect on how these guy's get these number's. This is especially true now with electronic's and the ease of reprogramming.
Ask for a legit dyno chart of your perticular unit.
When you read the dyno spec's, pay attention to the AR ratio's through out the range, especially in the mid and top. General rule you never want to be close to the killer number 14afr/95-96 lambda..LOL
Ideally your looking for a ratio ranging from 80 lambda 11.7 afr (rich) to about 90 lambda 13.2 afr (lean). There will be many contributing factors but this is a general good rule to fallow.
The C-tech is already lean so this would require a very good highly experience tuner to make it safe.
Learn to study the dyno chart not just for hp gains and torque but how safe it is through out the rpm range, avoid here say and inflated claim's.
In this case, this is what this is imo, big hp and torque gains, but not safe. Your dishing out the coin, don't think that the sell's department that sold you the upgrade stuff will cover you once your motor squeaks. understanding and knowledge is your own protection.

It just seem's that there are alot of so called tuning performance shop's selling these product with ridiculous claims, i have personally checked on some without naming names. They all appear knowledgeable on the phone but getting certain info such as dyno charts is like twisting their arms, they are more into trusting what they are telling you. BIG MISTAKE if you do.

So Lambda is "Fuel Lb/Hr" like it says on the Dyno report? I'm confused.

So interesting factoid today... Silber just released its ECU Reflash like PEFI today!!!
PEFI claims 8hp with all stock exhaust components
Silber claims 10hp with all stock exhaust components
As I alluded in previous post with this combo both are saying 15+ ish hp with Y pipe & can!!
Both Dynoed at 152 hp... so 165-167 is respectable for stock Ctech 800.
Also a very broad increase in torque from mid to high rpm.
Technology is making things interesting.

I want to see a stock, broken in, 19 on the dyno. Cat had these hot tunes on the early release 18s. If they were able to give most or all of that back for 19 then no need to get excited. Thd Silber setup is cool the way you can buy the cable and they can tune your sled over the web via your laptop.

It is
Ideal afr/stoich=lambda

So the numbers seen on that dyno report is in lambda, that dyno run was showing a AFR of approximately 14.1-14.3
