Attention: TDR Forum Junkies 
As many of you know, I have been involved in doing some Dyno tests for the Preporator fuel system, as is another of my local members. Well, today we "Base" Dyno'd the trucks at the AFE Facility here in Corona. Once again, I must say that they are running a first class operation over there- but that's another thread
.
I received my TAG from the group purchase about 2 weeks ago, but had not put it on because I knew that this Dyno test day was approaching, and wanted to do some testing with it. So we did.
We base lined the truck, which is as follows:
2001 HO, 275RV injectors, Edge EZ, stock turbo/14cm upgraded housing, AFE Stage 1 filter, ATS Manifold, Banks High Ram, Jardine 4" exhaust.
The baseline numbers peaked (as can be seen below) at approx 290Hp and 720Ft-lbs. These numbers were consistent with several runs.
The TAG was then installed, and two more runs on the Dyno were done, the results of which are overlaid to the original Base numbers.
I also sat in the jump seat with the Dyno Operator, to watch boost numbers as well as EGT's. Keep in mind that this is a Mustang water-jet dyno, with an 18,000lb load simulation. All tests were performed in 5th gear direct.
With the TAG in place, HP and Torque both came on slightly faster. The greatest differential was noted at 1670RPM, where the TAG yielded an increase of 5hp and 12 Ft-lbs. The peak Torque numbers with the TAG came in very slightly higher, about 5 Ft-Lbs, and peak HP was actually less (on both runs) by about 3Hp.
Interestingly, the EGT's dropped by about 50*, from 1300* at baseline, to 1250* with the TAG, and differences in Boost were too small to measure, both of which peaked at 32psi. On the road, I've seen both EGT and boost higher.
Since I've only driven the truck a bit since the TAG was installed, its hard to say there is any significantly noticeable difference, other than I "want" to believe and feel the "extra" Power. It does seem to have a tad, more go off the line. I have not noticed a difference in turbo noise, maybe a slight decrease, I know others have seen much more.
The TAG was also removed and Bench flow tested, on AFE's state of the art bench. The results, were that the TAG resulted in a 40CFM decrease, but it lessened the resistance of vaccume (water) by approx . 3 of an inch.
All in all, it is what it is, and while it did not increase overall horsepower, it does change the HP/Torque curve. Inquiring minds had to know
