13. We wrapped up the mechanical portion of this chapter, with an oil change, courtesy of an OEM Delco oil filter and Driven’s LS30 synthetic fluid. LS30 is specially formulated for LS-series engines, and we cleaned up any seepage with Driven’ brake cleaner (it works perfectly for stuff like this, too). Look for a more in-depth tech story featuring Driven’s full-line of products in a future article of GMHTP.
14. Off the lift, and strapped to the dyno, it was time to see the fruits of our efforts. Since Greg had an in-ground dynometer just literally a few feet to the right of where we installed everything, it made the most sense to use it to our advantage. As it turns out, with the tune ProCharger had previously installed, our horsepower output was a bit off from where it was at prior to the installation at 572 hp 577 lb-ft., as opposed to 576 hp and 558 lb-ft; down 4 horses, but up 19 pounds of twist. However, you have to keep in mind that the horsepower we managed before the install was on our above ground dyno at the GMHTP shop. Common sense tells you that no two dynos are alike, but since those rascals at Muscle Mustang & Fast Fords broke our dyno during their Open House Party, we had to roll with AntiVenom’s in order to complete this project on time.
15. Ok, so after all of that, what were the results of all of our efforts? Greg used his wizardry on EFILive, and managed to net us 590 hp and 610 lb-ft., or additional 32 hp and 52 lb-ft to the tires! It was a noticeable improvement on the street in the way the car pulled in acceleration on the freeway onramp. Our previous best time at PBIR's road course was 1:36, we we're curious to see how thei additional power will translate in quicker track times! Stick around for future installments; this is only the beginning!
16. As you can see from the charts provided, we were able to map things out like the injectors, spark, and other parameters with the help of EFILive. Since Tuning 101 is beyond the scope of this story, we’ll be bringing you an in-depth how-to guide with EFILive in the very near future, working with our project Trans Am WS6.
