As some of you know I am a dyno queen, test and retest every mod I ever do. Call it what you like but I personally like to know what does and what does not do as claimed.
To date the mods on the car are; Borla exhaust (no cats), K&N/Smooth tubes (no power gain), under drive pulley 25%, AEM unit.
For about 3 months now I have been driving around on the base map that comes with the AEM unit thinking that there was not much point to tuning on such a lightly modded car. After all the car felt fantastic, ran cool, smooth, etc...
But being the dyno ****** that I am, the urge kept nagging me to go and find out just what the AEM unit could do on my car, since the majority on the forums feels there is no gain on a light modded/stock car.
The tuning was done with daily drivability/poor quality California gas (91 octane) in mind. Could there be even more power to be gained? Yes, no doubt but with best grade of 91 octane being available around here doing so would be destructive.
First image shows the comparison of pulls; 26 pull shows one of the best factory ECU pulls which at 437.7 hp is fantastic on this particular dyno, stock viper make 396-404 here. Pull 27 is the base AEM map which was made on a 97gts stock I believe, and is the map I have driving around on. You can see significant gains over the best factory ECU. Now this is where it gets interesting, 32 is the last pull we made after some fine tweaking of the AEM unit for my lightly modded car (corvette guys would say stock).
The AEM unit allowed the car to make 452.5 hp and 508lb's of torque; this is at the WHEELS people.
This image is the only 3 tuning pulls we needed to make; yes you read that right took 3 pulls to fantastic tune. Most of the gains were seen in pull 30, but a bit of fine tweaking instead of broad adjustment got us over the 450 mark.
The best torque this car ever made with the factory ECU was 471lb's, and horsepower was 437.7. Both of which were NOT achieved on the same pull. The AEM unit allowed 15rwhp and 40 lb's torque gain. Notice the gain is not just peak numbers, it is all across the power band and the hp gains and torque gains in different parts of the RPM band are even greater than peak.
Now I suspect the many of you out there that have my mods along with some others like headers, rockers might be able to realize 500hp at the wheels and only God knows how much torque.
Thanks for reading, take care.
PS--This is my first time trying to post an image, and it is not coming up. If anyone knows how to make the dyno graphs come up right away please fix it.
