After running a long term test to see how well the stock PCM would accomadate the Heads/Cam Pkg. We reprogrammed the PCM to "Dial" everything in, to see the ultimate potential of the Z500 Pkg. The results... 446.9 RWHP & 418.4 RWTQ at peak. But more importantly, are the gains that were attained across the entire RPM band. The motor will spin 7200 RPM now. WOT @ 7000 RPM this thing has a Battle Cry from HELL!! The #'s are STD corrected, which is what Ed Wright normally uses. He is VERY knowledgable & was very meticulous in his work on my car. Ed was impressed with the results. He said that my car was the "Baddest" Heads/Cam car he's ever seen. After driving the car from Houston to Tulsa (600 miles) It was immediately loaded on the Dyno.We ran a Base-Line dyno, which I have included for comparison.
BTW, we averaged 24.4 MPG going & 25.9 MPG coming back after the tuning. The car idles & drive PERFECTLY, & is actually more refined than it was before.(And there wasn't anything wrong then.) The throttle response is even quicker & the car is notably quicker now. At least SOTP. I can't wait to get to the track.
NOTE: (For those that are gonna whine about SAE) Using the STD correction factor, the Base-Line pull was only +0.9 RWHP & -2.3 RWTQ different than my previous SAE Corrected Dyno results. HMS is moving locations right now & for comparison I will make some more Dyno(SAE) runs when the get settled.
We also made a N2O pull, but we couldn't hook up down low, so we punched it above 4000 RPM just to see if we gained anything. We put down 581.9 RWHP, a gain of 11.6 RWHP at peak over our previous pull. The RWTQ # was down a little from our previuos 688.1, which was at 3600 RPM. But that's because we didn't go WOT on the gas until about 4200 RPM. So I'm quite sure our previous RWTQ # could have been bettered.
I have posted the Dyno Graphs for your info.
