Extra 40?

and with a CF of .98

542 = 553 HP
528 = 538 TQ

???

Why wouldn't tuner use CF = 1 at sea level? Just curious or is that with calculating DA and all that jazz? Sorry i'm a dyno noob!

Unfortunately I didn't do one.

Not sure. Gonna require someone smarter than me

It's all good, I'm a dyno noob so I was just curious. Glad to hear the car is really fun to drive though.

I'm installing the P1X next week and we are gonna run 7 psi with a custom Dyno tune. I'm hoping for between 560-580 rwhp

What size pulley will you be running?

What is everyone with FI doing about gauges?

Aeroforce interceptor seems to be a decent choice - if you want to read boost you need to add the 2Mbar sensor, and then they have a sensor kit for Air / fuel if you want to read that.

Lol might want to contact ProCharger and talk to them.

I'm very happy with my Aeroforce!

Just load one of our stock files, log with his very calibrated equipment.
And said... "I not touching this file, this is spot on for a DI car, well done"

Nice pat on the back today.

At least they used SAE which is correct.
Normally you see them in STD which would have resulted in higher #'s.

Why?

That looks like a typical reading for a wideband shoved in the tail pipe.
That is the 100% incorrect way of reading air fuel on a DI car.
You will get a leaner than normal reading.

And these cars hate being rich. (for reasons I have listed before)
The LT1 is NOT and LS1, LS3, LS3, L99, LQ9.
You are very close to what it should be running AFR at WOT...

And that tiny percent I can almost guaranty is two things.
1) the wide band is in the tailpipe
2) sensor error.


Also looks like the belt needs to be tightened.
You boost curve has a wave in it, so either the following happened.

1) Belt slip
2) Traction control wasn't fully disabled, and the throttle closed for a moment

Since I see power also dipped there, it matches my theories above.
I would advise on looking into both of those.


NOTE: We use lab grade air fuel, and 5 gas analyzers here. Calibrated DAILY. We don't mess with air-fuel errors. We don't have the luxury since we have to do LV3 emissions testing.


NOTE 2: If you send me a datalog that actually has the wideband readin from BEFORE the cats, I would gladly adjust your tune if needed. Though you would be the first one out of a cubic boat load. Just an email away my friend. tuning@procharger.com

This was in no way a knock on your tunes! Like I said I'm very happy with everything you guys have done. I'm just personally a bigger fan of dyno tunes and the can tune is just to get the car to the tuner.

He doesn't use the tailpipe o2. His went in place of my o2 sensors.

At the end of the day I couldn't be happier!

Thanks sir....

I am just a little cranky after being around DI engines and tuning for about 6+ years. Just to hear "its to lean" almost on a weekly basis on something dealing with a DI motor and forced induction....(from people that have only dealt with port injected motors previously)

IF I had a dollar..... Id buy myself a nice steak dinner in Indy

But really, find that boost loss thing you got...
And I look forward to seeing your results with a file dialed into your fuel.

On that note, have a wonderful evening

Are you saying I should be making more boost than that?
