I recently have looked back at the post here and on other sites about the JWT vs Enthalpy 2871 comparison and there is something that was omitted, most likely unintentionally.
I think we need a little background here ....
Matt's (test car) ECU came back with small damage twice.. but was fixed..
When things were working correctly Matt and Cody told me that the car was running very lean.. so they got a series of retunes to try 10% and 15%...
Matt told me they stuck with the 15% richer tune and when he dynoed (at an earlier time) the AFR's were in the 11's and I told him he could make at least 10 rwhp or more.... because my tunes are spot on 12:1.... The 15% tune was definately robbing some power.
So here are the email exchanges ....

Matt,
Good to hear that you finally got the issues figured out. Just out of curiosity which tune did you end up using ? What are your AFR's now ? Any dyno results ?
Thanks,
Martin

Hey guys,
My car is running really good now. Thanks a lot i really appreciate it. I knew you guys knew this because you were in contact with Cody Ace.
Thanks,

We ended up using the 15% fuel increase and i believe the fuel pressure is somewhere around 50psi. AFR is in the 11's under WOT at 20psi. Dyno results were 380hp/310torque with it blowing out spark in the upper rpm's....Ill look for a dynograph and upload it if i can.
Thanks,
Matt

Matt,
Can you give me a run down of your setup.. I want to make sure that tune is 100% spot on for what you are running. The graph looks good.. but I want to make sure that you are not missing HP you could be making. Is there any way you can get a dyno plot of the AFR's as well ? Can you also ask them to do it w/o SAE correction and smoothing 0 ? That chart might seem like it's lost power, but don't take it to heart... it's just for my purposes, so I can adjust your tune.
Thanks,
Martin

Martin,
the setup
s13 sr20det (stock bore)
z32 maf
gt2871r .64 turbo (honed)
72lb injectors
jwt s3 cams
freddy intake manifold
20psi of boost
stock exhaust manifold (extrude and honed)
4.40 gears in the rear (not sure if this would make less hp or not)
stock coilpacks still
the dyno plot doesnt have AFR's cuz the sniffer was not working at the dyno, but i can tell you that the afr was in the 11's the whole time from me watching it while the pull was done.
i think the smoothing was on 5 when it was done.

Matt,
That looks damn good for a 2871 on pump. You would probably make 10 more by leaning it .5 AFR's , if you have that much room right now. Just keep it under 12.0:1
----------------------------------------------------
So basically the car is running on a modified richer tune from what I usually write for that setup at the request of Matt and Cody.. hence the loss in power. From what I was told the car runs in the 11's, where it should be drilling 12:1 perfectly like my tunes do. This will account for all of the difference if not more.
If the car were to run the tune I intended with no correction, the result would have been where it should be.
JWT tunes and my tunes are the best out there, but comparing one of theirs to one that IS NOT the way I intended, at the request of the customer is just not a fair comparison.
I wish that these facts were prefaced before this post was published around on forums. It is hard to take this with a grain of salt when you are in my shoes and had to issue $1600 for prepays in the last 2 weeks and the primary reason given is "I recently read/heard that your tunes don't make the best power etc..."
Matt and Cody are good guys and I know they never intended for this to come around and actually hurt me and my business in the way it has. Although I have a ton of dynos comparing my tunes to JWT in my favor, I never have posted them and never will.. and am compoundly frustrated at the fact that one of my tunes that was intentionally turned down was used in such a highly publicized test.
As far as my tunes go... the fact is this... I write each tune individually and can assure everyone that they produce the maximum safest amount of power on the market, as long as you are running what I originally intended.
