HP/VCM is not as complete as SCT with the parameters it covers on Ford but is better than SCT on GM. We ended up repairing a FG that was killing ECU's about half hour after being flashed by another shop using HP, they went through about 3 or 4 ecu's before the owner gave up on them.
mainline dyno sheets are based on road speed intervals, one car was a manual the other an auto, they will have different rpm for the same road speed, I have included rpm so you can compare that way
Correct It's a Borg Warner, it's a bolt on well it bolts to the manifold, everything else is pretty much custom would be a lot dearer than the GTX but has the bottom end and the top end, seems like a win win except for the set up costs
this car picked up an extra 20 rwkw's on the dyno with his old tyres fitted on the E85 tune, so no doubt this would have been over 400 on 98, his Pirellis did not like the power and the dyno
