Nice pulls and numbers.

Got the same care as you with around the same mileage [though just a different color], so it's cool to see a Pure setup running on top of it. I plan to go Pure here within this year at some point. Nice videos!

That was my first thought, if these are numbers with PS2's then that's not good at all.

Too low, you should get a Pro-tune or post up the uncorrected numbers.

Ill post the STD and uncorrected values soon. No need for further tuning. Timing was great, AFR was perfect.

Like mentioned, power losses through the auto/x-drive combo are considerably higher than a RWD/6MT car..

With a RWD/6MT and STD correction, the numbers would be in the 540/550tq range.

No doubt, I'm looking forward to it........keep up the good work

Very cool.

Take it to a quarter mile track and post the trap speed. That's the real "dyno".

Been running the 1320 for 20 years in 9-12 second setups

This will be breaking the WR this year... Last year with 2* of timing and 17psi, it went 11.78 @ 117 EASILY....

QUICK!

Here's the STD and uncorrected graphs.

Uncorrected figures is based on what the car made for ACTUAL power on this particular time, based on the conditions in the dyno shop. They were actually more favorable than an SAE/STD correction. If it was 100*F, 85% humidity, and a high barometric pressure of 29.92 in the dyno room, then uncorrected would be the LOWEST numbers calculated.

I have been keeping eye on it. Hard to tell from the videos posted the time between paddle pull and actual gear changes. It will be nice to see this combined with the PS2 and xDrive.

Because it's working the way it should. There's zero advantage for me going to something different...

its below 14:1 @ peak torque, and between 12.6-12.3 @ peak HP. Dead nuts exactly where I would want it.

So you tune for 2 points in the RPM range? Good luck with that. You can't get by with as much stuff with a turbo car as you can with a NA car. Just modify your BEF to fix it.

The flash is tapering the AFR well within an ideal range. Why change it? The power/tq is there, and it's been solid all all boost levels for months. There's really nothing to fix. If this were my 775whp 304" non DI modular motor, then yes, it would be entirely different on the AFR taper.

Can I get this flash even if I have the alpine already ?

So you think 15+ AFR at full boost is ok? That is above stoiciometric. Remember this engine is getting pushed just as hard as your 304" because it is only 183". I don't want to see you pop it because you didn't make a small change.

Dude it's a well known fact mhd is better than cobb. Not only because more tables are unlocked but it was brought up that Cobb had tables labeled incorrectly. Mhd is so much better but if you think your afr look good on a messed up tuned, good luck

Stop spreading bs. There is no issue with custom tuning with cobb. Mhd did claim cobb got timing wrong some how (never gave details). The only benefit of mhd is that they expanded upon the available tables. Namely vanos and valvtronic adjustment.

Mhd already has things mislabeled too. Labeling and scaling is a non-issue if you still know what to change to get the result you want.

No 15:1 afr isn't that big of a deal if there is no predetonation or knock occuring. The only issue with running lean is combustion heat. If the engine isnt sensitive to any increase in combustion temps then what's the issue?

Sometines you just can't win. We know nothing is "perfect", but when it works well, and you and myself know, why keep tinkering...

Outside of the numbers how does the new power band feel? I'm thinking of getting a PS2 (same car as you) just to get a flatter and broader power curve.

I'm assuming even on pump gas and 18 psi, the longer/flatter power curve would feel really good in comparison to the "peaky" stock turbo.

The gains are to be had through the entire RPM range. Since the PS2 can move enough CFM of air to (up to 26psi) around 6000rpm, this is where the big gains are are made, since the engine can consume more volume above 4500rpm. This is where the higher CFM of the PS2 can maintain boost target when the stock compressor is out of steam.
