As many of you are aware, we have been doing several TT installs and upgrades over the past few months - and with some great results. Much of the credit for these results need to go properly to Jason for a very fine TT package and an incredible, out-of-the-box tune, and to Torrie who has helped us a lot as we have approached and used additional modifications for even higher boost levels.
Jason's out of the box TT tune is nothing short of incredible. Most of you read of Skyrex's accomplishments at the mile more than a year ago with 20+ runs over 200MPH. Apollo and AlohaGT also ran passes at the Texas mile with great results using Jason's tune. EXTREMELY impressive.
Lately we have been increasing the boost levels of some of these cars and have added the Kenne Belle Boost-a-Pump system for extra fuel capacity at the injectors. In order to tune for the additional mods, we have been working with Torrie on custom tunes. Mind you, we had very high expectations as we were coming from tunes that worked perfectly for us - but we wanted to exploit the additional mods. These tunes from Torrie have every been every bit as remarkable - safe, strong, and reliable as Jason's supplied tune. The really cool part is that Torrie has been just super to deal with. We have to schedule the availability of the car, the dyno shop, and then typically last, we call Torrie and see if the exact time that we have chosen will work for him. He has never turned us down!!
Just one example of his experience and professionalism was visible last weekend when we were testing a TT on the dyno. Working with Torrie over the internet, we set up his custom engine parameter capture program and datalogged the car throughout the dyno pull. During the pull we are observing the car and A/F ratio to keep the car safe. As soon as we do a pull, we email the dyno log (hp, tq, boost pressure, and a/f's) as well as the engine parameter capture over to Torrie. Torrie looks over the files and results and makes the modifications - just as he would if he were at the dyno. We only introduce the latency of emailing tunes back and forth. So, last Saturday, we run a newly configured TT up to 11 psi and 6000 rpm and everything tests fine. Torrie gives us the green light to command the car (via the in-car adjustable boost controller) up to 20 psi. We do this and do the run - all the while watching for good a/f's during the pull. The pull goes well with good a/f's and (850HP at 6,000 RPM) which is right on the curves for Apollo's well-running TT. Instead of emailing us back an improved file and letting us go up to our desired 24psi (1,000 RWHP) Torrie calls me and asks what the heck is going on with fuel pressures. It seems that from ~4500RPM to 6,000RPM the rail pressure is rapidly going down which is something that we don't want to see. In fact, you'd like to see FP going up with boost pressure to make the injectors appear larger. Normally, Torrie would like to see 59 psi. With this car we are at 39psi. Now, with all of our safeguards in place, we likely would not have let anything happen to the car but clearly there was no need to do another run until we could track and fix this problem.
The point of this is that the experience and professionalism of Torrie with respect to the tuning of GTs, he is a king. I count on and trust him a lot. The icing on the cake is that he is always so easy to work with and so very accomodating to our weird, West Coast tuning times. If you need a tune for your a GT he is definitely the GO-TO guy!!
