I went up to Louisville this weekend to meet Chris Ludwig to dyno-tune the engine he just rebuilt for me. We were on a Mustang. Before I reveal the results, I thought I recalled a discussion of how to compare Mustang and Dynojet rwhp, but I can't find it. In the range we are talking about for a 2nd Gen., how many rwhp would think you should add to Mustand nos. to equate to Dynojet? FWIW I'm really happy w/ what we got.
