You obviously are more then qualifed to dicredit his research, work, and credentials. So why don't you go ahead and tell us what your "research" has turned up that proves Jim Wolf knows less then everyone thinks he knows. I'm sure we're all dying to hear it.

I think JWT used their fuel solution as a cost effective solution, whereas APS does not care to keep costs down, but to "over engineer" their systems.
Case in point, pick up any pipe from and APs kit, and compare the inside finish and welds to that of the TN, or Greddy for that matter..You will see that APS grinds all of its weld smooth, and finishes every sinle pipe flawlessly.This acomplishes 2 things.
1) to reduce any restriction in airflow
2) to keep and pieces of excess welds or debris from being in the pipe where it should not be.

Now, show me one TN owner that has successfully run their stock TN fuel system over 450whp for over 30,000 hard miles...You can not..I assure you.

APS Constant Differential Pressure
Fuel Rail Pressure

Injector Orifice Pressure Difference

Fuel Rail Pressure

Injector Orifice Pressure Difference
0 psi

58 psi

2 psi


60 psi

4 psi

62 psi

6 psi

64 psi

8 psi

66 psi

10 psi

68 psi

FYI thats from the APS website..


Looks to me like the base pressure is 58 and it goes up with boost as it should with an rising rate FPR installed.

From what I can gather, JW is smart enough to surround himself with people that are knowledgable. In the end, just my opinions and just what I had found out asking about JW. I don't plan on running his kit, or any of his parts so it really doesn't affect me.

I can show you an APS twin at 10 psi of boost that made over 460 to the wheels for 35000 miles until he hit a tree, and he is using the same fuel system and engine management as the APS single FYI..The same engine management TN copied on their stage 2 kits.. Cause it works..

Turbonetics parts are made in Mexico?
The intake piping is not aluminum?
The Turbonetics kit runs extremely high fuel pressure?
The exhaust piping is not Stainless? (BTW I've seent he pipe welded on, its stainless)
The fuel system is maxed at 7 PSI?
The car runs 13:1 AFR?
The fuel system will not allow more power over 8 PSI?

Yup you are more then qualified to judge a design and more so set design parameters in an engineering practice

I didn't say: HERE IS MY PROOF!!! what I said was Besides, most informed car enthusiasts can look at his fuel system and know that's not the way it should be done


And I love all this talk about stage 1, stage 2, stage 3 etc. I am holding out for stage infinity - mai, and word on when such a stage will be released

#2 I have datalogged several TN cars where the stock injecotrs were maxed out past industry standards at 7 psi and 100% duty cycle at 8-9 psi..
#3 Not every car runs 13.1, but the one I saw bend a rod did...Car simply ran out of fuel up top..(we did not do the install)
#4 the stock TN fuel system and ECM is a ticking time bomb imo...An RPM based tune of a bosted car is simply stupid...The ecu can no account for more boost,denser aircharge,air density ect...

Please read all my posts before makjing your ignorant comments fool..

But how would you even know that since its not released and unless you made a trip to Turbonetics recently and they showed you I don't think theres anyway for you to even guess at whats in it. And again: SHOW ME ONE APS ST MAKING 450RWHP FOR THAT AMOUNT OF MILES

Oh and it appears that several APS owners have asked about upgrade or "stage" kits from APS but they aren't planning on doing it at least for the ST kit. So I guess its not just Turbonetics owners who see that not everyone needs a kit capable of 600 HP. Some people don't want to pay for parts they dont need when they are only planning to make 365-380 RWHP so why not provide them with different paths to take to meet their goals. The customers asked for it so Turbonetics is doing it. But then again I guess APS doesn't exactly have a reputation for their customer service now do they?

Basically, what more than one shop told me is that JW couldn't tune a car to roll down hill in neutral - but then again, as you pointed out, no shop I have talked to is qualified enough to make such a statement, so I will let people find out their own info and decide for themself

I have no doubt that the Uni Q will be superior to the old Unichip, and once it is bug free, I am sure APS will make the transformation also..My point being is , TN used a half a s s ed reflash for over 2 years while APS was using Unichip technology, which may not be the best, but far superior to that of a base TN kit...Now TN sees this ans decides to jump on the Unichip bandwagon, cause it works well and is cost effective... Technology once again proved by APS for over 15 years.. Now, Obviously you work for TN as I see you resorting to the same "know it all" tactics on every forum out there, something someone who is not collecting a check from a company would never do, unless your just on someones jock and trying to get brownie points..
PS, when is the relase of the stage 2-3-4-5-...????
