I was basing it off of what I know and the data I have which is wheel HP. The stock setup is around 150 wheel and 6 psi on a bone stock engine made 250. So, roughly 70%.

Dyno sheet results or math wise?
What boost calculator or combo out there nets 70% gains off of just 6psi ?? I cant find it.
The ones I use, even off RWHP being 150hp + 6psi = ~211rwhp (~<50% like Banks advertises) You will lose more thru 4WD also

Its also quite a stretch to say Banks grievously underrated their product by 20% when theyre in the business to sell HP. Call me crazy but…..

I've heard its pretty good. I see a LOT of trailblazers locally that are rotten to the core still running and driving around with 200K+ miles.
Dyno sheets and videos if you feel the need.
Banks used an old school now outdated turbo for their kit. The newer stuff is much more efficient and has almost no lag.

The video owner / seller responded saying just under 7psi. Cant tell what boost there is from the video, or any other mods
However, every calculator that works off boost mathematics shows ~10psi required. This is something Id literally have to see in person
Its hard to believe , but Im happy for those that have bought it, and Banks Power should be notified to comment

Fwiw, I was concerned about turbo lag but haven’t noticed lag issues from the air-to-water intercooler or the turbo that Banks chose from a Volvo C70.
The load relief in stop-and-go is noticeable because it comes on early enough in the RPMs. The turbo generates at least up to 13psi, but I have the Turbosmart actuator set so I max out at 6psi.
If it was practically possible, I’d run a newer style turbo in its place, but all seems to work well as a package.

Might try reading up on what he's done and the kit that he's designed.

I did the dyno tests. You're right the boost spiked close to 7 and then stabilized at 6.5. I call it 6, you say 7
.
Engine was stock internally. It also had over 200k miles on it. The only other mod was a catback pipe.
Boost calculators are BS. 20psi on a little T25 is much different on a GT4202 or a PT118.
Banks doesn't care. From what I understand they were having a difficult time getting turbos, and instead of reworking the kit they dropped it from the product lineup.
At the 3:11 mark in the video I think he means: NA power * (boost/14.7 +(1))
Not what's written in the video: NA power * (boost/14.7) +1
My understanding is that they stopped because the 99-04 kit wouldn't pass the new CA smog tests...even though the 05-06 still passed the new smog requirements.
Their turbo is a Mitsubishi from an older Volvo C70 (and other Volvo models that I have saved) and is still available. However, the stock Mitsubishi turbo doesn't have the Banks machining to mount with their engine/alternator bracket.

What’s the total approximate cost to make the LS3 swap including under armor?
Trust me I’m no hater of the LS engine (dad and grandpa are retired GM).
But if I can save $10k+ by doing a turbo and it provides enough power to make me happy, then who cares if someone else thinks the LS is superior.
Not to mention that if I take a job in CA then the LS swap becomes a liability unless I play the game registering somewhere where I won’t actually be living.
Point being, there is no one-size-fits-all answer in case you haven’t figured that out yet.
