Were the stage-3 is not heating up the charge as much that makes a big difference on a track car or somebody doing de's. I would perfer a little bigger turbo to be more in the efficiency range.
But $300 is wayyyyy better than $3,000

........ Great chart Russell.......
But I have been lurking on the list long enough........ that chips and 16 psi on a stock 26/8....... do not equate to these numbers.
A 26/8 pushing close to 20 psi with a proper tune is seen at ~280 hp/350 lbft on an extremely good day.......... and at that point most are trying to bring down the heat via water injection etc. No matter how much fuel you throw in there to cool things down.......
I can see 18-20 psi with an extremely aggresive timing curve hitting those numbers......... But 16 psi???

There is no boost log in that chart , it will be nice to see the boost curve as well. 302whp & 345wtq @ 16psi from a k26-8 is hard to swallow. I am not flaming either but I have tried several turbo combinations at different boost levels with differents chips and also a piggy back and those numbers fit between the 18-20psi range for a k26-8. In order to achieve those numbers @ 16psi in a 2.5l engine, you will need excellent compression (like new)the leakdown under 2% in all cylinders and lots of tuning. If you have the boost log or a video of the boost gauge while on the dyno it will help a lot.

Not if:
A. the 16 psi is being held to redline
B. proper tuning to allow enough fuel/timing to make power and still cool the charge from the heat.
C. that 4" exhaust might make a lot more difference than people think.

Good numbers, seems a bit too high though.
People need to remember one thing and that is that there is nothing magical about chips.
Yes it takes lots of testing to come up with the best possible values but there is nothing that magically can release like 30 horses without changing boost if the previous chips weren't horrible to begin with.
To get maximum peak numbers on a full throttle run you can only do so much as make the timing as agressive as possible (read: as close to detonition as possible) with good fuel ratios.
Drivability and tuning to be able to run high boost etc. is a whole different thing. But at a certain boost level, on a certain configuration. Chips alone won't change peak numbers with +/- 10-20 %.
BTW I develop and sell chips in the Nordic countries so I do know what I'm talking about..

345 tq @ 3800 RPM = 20 psi
See this thread - the first run at 20 psi and the last run at "16" psi, have almost identical torque around 4K.
