I dont know what the delta is between DynoJet and Mustang but have heard 15% to 20%. At 15% that would put my max whp at 373whp and 394wtq. I guess I will have to find a DynoJet and see for sure.

I have about 250 miles on the new setup and the car feels GREAT! Everything here is wet these days so I can go out and give it a good test. What driving I have done says the car is quicker and stronger.

I will send the data file to Jerry and see if he thinks we can tune it up more. You can see my AFR was 12.5 to 12.9 on the dyno and the boost was at 18psi. I hit 20psi at the track before the modified mani's. I am VERY happy with the mod and it took my 1/4 mile time from 12.5 to 12.2 on a track that wasn't prepped. Did I mention that I was happy?

+12 Hp and -.3 off your 1/4 mile time are great results for the money...

Get the 100 octane "hot tune" chip from Jerry and next season at a sea level track and your --deep-- into the 11's........
