Hey guys, dyno'd my car today at a dyno day.
The car is a 99 ACR with cat-back.
Below is the dyno:
Seems like it is down about 20hp. There was another Viper there with similar mods that did 425hp.
What I noticed on his dyno chart is that his AF was a bit leaner than mine (looked like a full point).
Does the AF on my dyno look a bit too rich? Wondering why if thats why it only put down 404.
