So here is a comparison...

The higher number was the pull right after the turbo's were installed.. car was driven around for a short drive to warm up the components, then dropped on the dyno... the lower number is after I drove for 2hr's down interstate 95 in traffic, then dropped on the dyno.. it was also much hotter and more humid that day as well..

The peak numbers are different, but look at the curves.. they are identical. So what this tells me is the car was running exactly the same both days, but either I was pulling power the whole time from heat soak (which it was) or the DYNO was calibrated slightly different that day as well resulting in a slightly lower output. However, the point stands that the curves are IDENTICAL but peak is is off by a couple percentage points.

Yes it's identical and gives a look inside to show how much weather/heat affects our performance.  Overall its not far off which is great news.

3.8% difference between the runs.  I guess what I am trying to say is, don't get hung up on peak numbers :-)

My shop was kind enough to provide me the dynojet files from all my runs so I can play with them as I need to... dynojet software is free.

I won't get hung up on peak numbers now that I know what's really important.  I guess now its just to have a power reference.  Plus its just cool!  Thanks for all the info!

Manu you were right!  After having DTC P0130 and P0150 at the same time you suggested to clean the sensors before buying new wideband.  So far so good on cleaning my 3bar and IAT sensors before replacing my wideband oxygen sensors.  I cleaned them...at the same time which I found they both have the identical part numbers....is that correct?  My 3bar and IAT sensor are the same?  I then swapped out my sp534 plugs with the sp542 plugs all gapped to about .027-.028.  Brad asked me about my Meth settings and I think my new pump is more powerful than the last as he made remarks that I was spraying a lot....I kept my settings the same and just swapped the pumps.  I decreased the initial by about a quarter turn and also increased gain to 8 to start spraying at 8psi.  We make boost so damn quick I don't think I need to spray at less than 8. 

Took it for a warm up drive then two data logs.  One from a dead stop, no brake boost just a hard WOT 1,2,3 gear sweep.  Then another at about 2,000 rpm in 3rd, WOT 3rd gear to about 5,600 Rpm.  That's it.  It felt better I must say and my check engine light did NOT come back on.

The 3 bar on the intake manifold (factory is 2 bar) and the CAC/IAT2 sensor are one and the same, yes.

I spoke too soon.  As well as my two datalogs felt last night I did have some fuel pressure issues, primary sensor bank 1 had problems which affected it.  Bank 2 is probably right there as far as needing to be replaced as well.  So I will have to replace both primary sensors bank 1 and 2.

It should resolve your issues and should always have them replaced in (pairs) especially the wideband 02 sensors since they control (AFR) and don't want to throw off one bank! Z

Swapped my primary 02 sensors last night bank 1 and 2.  Purchased an 02 sensor swivel wrench that made this quite easy.  I was able to get both front 02's from the bottom of the car.  The only thing I did from the top was harness connections.  I did employ SBS's shoelace trick.
They 02's look pretty well done....left wayyy too long on the grill!  These puppies have never been replaced by me until now.  That's 20k without an issue.....how long they were there when I got it Idk....and out of the 20k I have been tuned for 14k. 

I was fortunate that I was able to read up on old posts of swapping these out....and buying the wrench in the pic below.  It made this experience not nearly as bad as some of you doing this without others previous experiences shared here.   For that Thank You!

For others wondering the pigtail lengths are the same, it's just one part# DY-1120 you'll need and if replacing both banks just order 2.

SBS and I used the shoe string method for the connectors.  It save me a lot of time and a lot more colorful language. 

Andrew I know quite a few people here will see your thread and start the process of changing their O2's as well.  I will save you some time and drop some knowledge for the people wondering what is involved.

Thanks buddy.  I thought I should do them...but my mods this year have got me well over my 6k budget...so I skimped there...could have been changed easily when the subframe was down and everything wide open...nope..not me...end up needing to change them after with everything back in the way.  That swivel OEM oxygen sensor wrench saved my a$$.

You and me are alot alike.  We seem to like to do things the hard way lol. Cutting the wires and the shoe string saved me.

Haha I almost ✂ them too!  The rear I had to disconnect my lines to my catch can and get all that out of the way.  I looked once and thought ......where are my dikes...then I stopped...gave it another try.  I pulled the wire plastic clips out, pulled the whole connection right up into view, then disconnected them.  Haha after I did that I thought...not bad!

I would of just pulled the downpipes out. I like creating more work for myself. Andrew how many miles are on those buddy? My car just hit 70k I can't only imagine what mine look like.


Never mind I actually just read your posts lol
