I doubt I have the fastest GTS especially since I have a Targa, but that was never my desire.
I always want my cars to be different from the pack. Color, Speed, Stereo, etc..

There is no doubt in my mind that your car will be faster. Stickys car will be faster. I want the best bang for the buck and I think I got it.
If you want to bolt on bigger turbos, intercoolers, meth injection..then you will smoke me and thats fine by me

I will re start my feud with you 4 point 0 that the IPD plenum does nothing and that all of these headers essentially perform identically.
I think once you get into pro tuning you may find the same thing

We may be waiting a lifetime for Sticky to do his header testing as I dont think it will ever happen...

..
I can accept that all equal length, ceramic coated headers will perform very similarly. But a non ceramic coated, non equal length header will not be in the same league.

As for the IPD, everything is relative. It does nothing when compared to a COBB tune, or compared to equal length ceramic coated headers. But It might do something when compared to a BMC filter. (Which is not much)

We can agree It won't be the IPD that makes the difference, it will be the 50 Hours of Dyno time and 100's of hours of track testing that will make the difference.

4 point 0: you aren't understanding what I am saying and I have said it repeatedly...

The IPD plenum will do NOTHING for performance. Not nothing compared to a 100hp Cobb Tune, I mean it does zero, zilch, absolutely nothing at all for the engine performance.
I just wanted to make myself clear so that anyone reading this understands my position on this. It is more likely to DECREASE overall performance than do anything positive, so actually it may do something

I am also not 100% sold on the header gains.. I am still on the fence about their overall benefits as well. Again, would love to see more independent testing on this.

From the dyno sheet that appears to be a Mustang dyno, they measure the power differently than a Dynojet dyno and they do read lower. I bet you're another 30+ whp/wtq on a Dynojet. Also will depend on the correction factor used, too.

Best and most accurate dyno is the track 8-]

Nice numbers!

How about their Y-Pipe? Any improvement over stock With that?

Any pipe that will eliminate the cats will improve HP. No idea about anyone specific pipes, but a straight pipe has been shown to provide the most gains.

Thought you were referring to their intake plenum. The IPD Y-Pipe goes into the manifold plenum.

This is the part I am referring to:
https://www.ipdplenums.com/products/...arrera-s-turbo

It makes no gains in HP or torque but some people buy into their claims. I have been pretty vocal on the forums about how worthless this part is.
Been out a while, still no independent dyno results showing anything near their 30-40 hp torque gains...

I emailed them to Psorcery so you can ask him to extrapolate them and post them in this thread. He's had them for hours

Just curious when whoever was reviewing your logs says that 90% of knock is gone. What metric was used to show this? Also wouldnĺt any knock at all be bad?

Regarding the the comment that they are curious how they got more power and torque AND it was lean, itĺs my understanding from my piston flying days that peak power is made lean of peak cylinder temp. Iĺm sure there are many other factors but from what we could control, full rich for landing and take off and in cruise lean it out for max range, and power at a particular RPM and MP.

With all due respect PTS your datalogs gave me a headache. Just post them up and stop fearing for your identity.

Does the Cobb Pro Tune work with the PSE option?

​​​​​​No, it would be pretty impressive if it did. But no.

Same part I was referring to...they sell a Y Pipe as well that goes into it
