Honestly, his numbers are what I'd expect with that turbo on a 1.6L on a roller dyno... I see nothing wrong. also I thought you were running like 15psi and had a major boost spike during spool...
add a mere 10% to his numbers and you got 247/216 for a rough dynojet comparison.

Buffon, since there are so many correction maps, the afr fluctuates quite a bit depending on so much.
if im on a level, no throttle inputs, in 5th gear on 3.6 rear end just cruising... it will vary between 15-16.5:1
The main thing is that i cruise at 70mph (110km) at ~3k now vs the 4k with stock 4.3 as well has having VTPS and a tune very specific to my car...
This could also attest to the quality of the injector dynamics injectors that i picked up from 949 racing.

This is visually observed over 1 day. I will datalog some driving in the near future, as i need to get my boost control running anyways, and then i can see what the ems is recording which is more accurate than me reading my innovate guage.

No it was at 12psi trailing to 10psi cause the stock greddy wastegate wasn't working. Then I upgraded it to a t28 wategate and set the MBC to 14psi and got a steady 14psi all the way to redline but I haven't dyno that yet. The boost spike your talking about is my current issue with the new IC I installed.

I think his numbers are good. It took 16 psi from my 2871 to make 242/224 on a Mustang dyno.

That makes me feel better about it.
I want to **** around with boost control still to get it up there and steady.
If i can get that working, I will make the 2 hour trip to toronto for the M-tuned dyno day and run it on their mustang for number comparisons.

got bored... overlayed my graphs that i have.
low lines are 10psi
high are 12psi.
i never drove the car at 12psi. :(
When i get the new turbo i will get the same charts with the same turbo, only difference will be the TiAL exhaust housing... i may tune up to 14psi too...
This time i will have cometic head gasket and ARP head studs since my head gasket is leaking like a seive.
EDIT:
Does anyone have any insight into why power was falling off at 12psi besides the possible boost drop from not running a real boost controller?(we used a crimped metal T since EBC wasnt working and i didnt have a manual)

The gt2860rs needs 15psi or so to "work." I don't know why but on my old begi stuff and my absurdflow stuff my car made **** output at 11-13psi...then at 15psi its like another world. I'm sure that my lowered compression has something to do with it too.
from the old begi stuff...

I was creeping the dyno section today and i noticed this in your dyno thread.
being on a completely stock engine im weary of high boost... but im going to add a knock sensor to the EMS and watch that.
My tuner told me this at the tune day. he said another psi or two will liven this setup up for real.
I was getting scared that day because the higher we boosted it, the more oil i was leaking...
I hope to get some solid numbers down and pump 14psi into the engine with it being happy.
Im also going to try to tune a bit more of my 2000-3000rpm cells to get better in town drivability... the 1.6 fidanza seems to make my car not like holding between on/off throttle.

You are running the 0.86 TiAL housing, correct?
