I have finally decided to take the time to write-up my experience at Japtrix Racing in Riviera Beach Florida, where I had my MSP tuned this past May. For those that just want to see the numbers, well, you will have to scroll down a bit, because I am first going to blab on about my entire four-hour experience at Japtrix.
First off, the facility was about as clean and spotless as I have seen at a tuning and installation shopit looked like I could eat off the floor! The staff I met were a friendly lot, and treated me both professionally and courteously. They offered to buy me lunch, but I tuned them down and instead accepted a lemonade. I must say, this is precisely the kind of service that will keep people coming back, and from the looks of things, they are doing very well.
Jack was in charge of setting up my car on the dyno and educating me about the tuning process. Roger, the owner, did the actual tuning of the Unichip. Both he and Jack asked about the type of mix I was injecting with my Coolingmist progressive water/alcohol (W/A) injection kit. After some back and forth, they convinced me to dump my 50/50 mix of distilled water and denatured alcohol in favor of 100% methanol. Jack promptly drained my 50/50 mix and filled the injection tank with 100% methanoland did not charge me for it! Moreover, Jack fixed a small leak I had by the checkvalve. By the way, I paid a flat fee of $500 for the entire session.
I recall that they did about 8 or so pulls before they were satisfied with the tune. They use a Mustang dynamometer at Japtrix for all their tuning. The jpg files below contain the initial (or baseline) pull, the final pull, and the baseline and final pulls overlayed on one graph. For reference, the blue line represents whp, the green wtq, the purple/pink boost, and the red AFR.
Some may recall that I reported on my dyno experience (no tuning was done) at Central Florida Turbo (CFT) in February of 2005 in the tread:

At that time I had all the performance modifications I have now, except the Injen CAI and the Coolingmist progressive W/A injection kit. On high boost and Map A I recorded a peak 180 whp and 180 wtq on the CFT Mustang dyno. My base pull at Japtrix was 182 whp and 181 wtq, which is awfully close the the CFT pull just noted. This is consistent with much of the received wisdom on the Evo, SRT4, and NASIOC borads, to wit, simply adding W/A injection will not, in general, yield significant gains, as you have to tune for it.
My final pull at Japtrix yielded 202 whp and 193 wtq. More importantly, the area under the whp and wtq curves (i.e., the integral of the function that represents those curves) was significantly increased. If you look at the third file, at the top end, I am putting down approximately 27 more whp and nearly 25 wtq than my base run. The car wants to pull right through the redline to the rev limiter without a hint of a power drop off.
Generally, Roger pulled some timing and added some fuel in the 3k4k range, so as to avoid knock in the maximum wtq area. Then he added timing back in and gradually pulled fuel after 4k, and also added more boost from about 3.5k and up. Up top I am now holding 9.5 psi, my AFR is 11.9, and my timing is advanced around 2224 degrees. My methanol to fuel ratio is about 25%.
What's more, with the Unichip boost controller off, the car now pulls about as hard as it did before my Japtrix visit with the Unichip boost controller on! What a fun day!
