Predator Custom Dyno Tuned LS2 Today I went to my local shop, Dynotuned Performance in Chesapeake, VA and picked up my brand new LS2 Predator they had ordered for me. We get ready to custom tune it. We strap it down and run a baseline. Baseline before was 383whp, since then I've added a t-stat. We strapped it down and it made 386whp. Basically 3whp for t-stat. We then download the regular predator preset tune into the car and dyno it again. This time it makes 390whp. A/f is in low 10's from 5k up, so obviously we had some room to work with it.
After fiddling around a few more runs we consistently was getting the same numbers and a/f was right around 12.5:1. Final numbers were within spitting distance of 400whp.
The last runs under the 12.5:1 a/f were: 399.9whp/396.8wtq and 399.3whp/397wtq
Needless to say we were all ecstatic with the results. All were done on a dyno dynamics dyno sae corrected.
