Well this is just a bit lower then what most people are seeing with the magnacharger with fuelrail fixes and tune. ( just side info )
EFI is showing that same pull for HP ( Using vehicle weight at 3775 for the GTO ) HP = 469?
Now even more info on this is that I am showing with EFI constantly the HP over 400, which is what it should be.
So my question is, could the dyno really be that far off?
I was assuming that the efi showed the real world number closer to what a mustang dyno showed.
although very interesting
336.5 /.9 = 373.8 mustang to dynojet rough conversion
373.8 /.8 = 467 ( what is what the fwhp for an auto should be ) Is this what EFI is displaying, just wondering since its almost identical to what was reported.
