ok one thing im noticing is that when im at idle and im reving at exactly 6.5K rpm I get like a pop but then stops once th rev pasts that 6.5K rpm marker and when i decelerate i get another POP at the same 6.5K rpm
But my STFT is at -0 and -1
and my LTFT is at -1

Another thing is when im actually driving my AFR's are mid 12's and mid 13's
Its only ad idle when im reving 6.5 RPM that it goes to 11.1 is this normal? and once it passes 6.5K rpm is goes back to mid 12's

actually as jeff explained about 20 times now, STFT is useful only to look at for a short time when your idling after a reflash... after that the LTFT becomes what the STFT use to be (STFT will head towards zero) and the two basically add themselves together for an overall fuel trim.

Read through this whole thread and you will find answers. I know it's a pain, I had to do it. While cruising you should see AFR's of high 13's low 14's at WOT or high load they should be mid12's to mid 13's. Stock AFR at high load or WOT is low 11's as I can tell from my data logging. If I'm wrong someone correct me.

unfortunately for me, I'm generating so much power I do not floor the throttle anymore unless I'm already moving at a good clip. I don't want to replace my transmission.

So I did some logging today with the EFIDude prologger, I have attached the file for anyone that wants to see it. Unfortunitly you need to download the prologger software from their site. Go to http://www.efidude.com/ and go to downloads and download the prologger (not the drivers). Once downloaded you open the prologger, click on file then click on import. At this point you import the file you want to view, it will prompt you to enter a vehicle description (any name will do). Next click on VIN and choose the file you named. Now you can pick what parameters to view (3 on top and three on bottom).
My observation:
Not sure why load is more then 100% but oh well. Looks like WOT AFR stayed mostly in the mid to high 13's with a few 14.1's sneaking in. I think this is right on target? Cruising AFR (bellow 4K RPM) stayed around the low to high 14's. I'm guessing this is also on target? Cruising at more then 4K with some light load showed AFR of 12's and 13's.

both of those are on target. keep these numbers in mind, 12.5 - rich best torque; 13.3 lean best torque
those are only for N/A though. FI has different numbers

har har har.
When I setup my boost controller, I ran back to the dyno expecting to make more power. It felt like I did, boost came on 1,000 rpm sooner. I ended up making 15 whp less.
So I cannot even guess the number since I'm horrible at it.
It will make whatever it makes.
I just got off the phone with TurboXS. I should have my exhaust in 2 weeks. Then I can compare my current 2.5" to 3.0" and get an idea exhaust gains with turbo.

I haven't gotten my Cobb yet but can't wait. How long did it take you guys to get yours? I ordered Saturday night.
mysql---- lol, now that I look at what I said it does look like I was joking, I wasn't though. One rumor was it was just a 3 day ban???

I hope matsuyokozuni doesn't comeback on here or they may extend it...
This place does get kinda dull without MM around, mayhem is needed in these forums
But seriously he is the most active typist on here when it comes to suggestions for problems, and always improves on existing products. This place would be lacking severely if he was permanently banned

thats crappy, even though i have been there and done that.
i am trying to think why you would make less hp at a higher boost. maybe intercooler efficiency?
