HP Tuner Log File: Please have a look for me. Car is down on power, and I have gotten HP TUNERS to try and fix my problems. I have a scanned log, *.hpl file.
LOG FILE
Can someone please have a look at it, and let me know if anything looks out of whack.

My thoughts.
Not once in that entire log did you go below 1600 RPM's.
You have some KR in some areas that can be worked out. (use the histogram to see)
LT FT's are very negative.

Yeah up to 3-4 deg of KR, on WOT.
The LTFTs seem to zero out on WOT though?
Yeah never went below 1600rpms. I was driving from GA to NC and it was interstate driving. Figured it would give me a basis though.
Suggestions on where to start?

What mods does the car have?
Your LT's zero out at WOT because they are - before you go WOT. If they were + you would have a + LTFT at WOT which is undesireable.

Thats about it engine wise. Seems to me the MAF and MAP rates are off as well... the engine should be taking alot more in

Something is unusual with your log file. I converted it to Excel to do some analysis on and noticed with my software that I was getting some erroneous data in the log file. I checked the Excel file and noticed that on your WOT pull starting around Row 3062-3065.
Look at your MAF Row and your Injector Duty Cycle MS (Bank 2)
Values: 17.1, 32, 28.9, 17.4, 17.3, 31.2
This would put you much greater than 100% duty cycle on Bank 2 which at that RPM does not seem consistent as it stabilizes out as it gets passed it up towards 5100 RPM.
Your MAF Rows in that range also have -28.53, -28.53, 0.31, 0.31, -28.53, -28.53 values.

No, no wide band. And yeah it seems to be .900mv sometimes which does seem rich.
Hmmmmm now I am really confused. Not sure why I would be exceeding 100% duty cycle, unless it really is bad data.

I would only dhave back a little, if at all on the PE
until you have a wideband. One side looks close to
the value I saw matching 12.8:1 (870mV) while the
other is a bit higher; who's to say what's right? The
voltage drops slightly which could indicate you want
a bit of a rising rate on PE w/ RPM instead of a flat
profile.
See tip-in KR that is large and hangs on too long.
Cut your Fast Attack Rate to something like 0.1
and the decay rate to 0.2, and this will reduce the
effect of this KR on you by a lot. Also look at
increasing your VE table in the MAP=12-13 (convert
to kPa) and RPM=2000-4000 range. Might lower
your PE %TPS vs ECT threshold to bring it in a bit
sooner. But I think your SD tune is lean and can be
fattened up there to mellow out throttle / MAP
transients.
See one WOT segment where the MAF appears to
be plain cutting out on you. That's abnormal. Might
check connections. Any power problems?
You are running well less spark than you could, is my
impression. Get the transient KR squashed and maybe
figure out what's up with the screwy MAF dropouts
and you can probably push another 5 degrees across
most of the 4000-6400 range.
I think your MAF may be reading kinda rich as shown
by big negative trims and a higher CylAir than I get to.
This would affect your spark some.
