Different dyno with different answers
So had a interesting day, went to a Euro car show with friend for fun. I run into a portable dyno and am like why not, they were doing 3 pulls for $70 and my car has never been on a rolling dyno. It has been on two dynojets a few times (which were consistent with each other). So the last time I was on a jet (hub mounted dyno) with all my current mods The car put down 420hp and 358 tq in a cool 55 degree enviorment on its best run without nitrous.
Today was in the high 80s and muggy but all the same, on the Dyno Dynamics portable my best pull was 370hp and 410tq at the rubber...

50hp different between the two different kinds of dynos and 50 tq different
At the end of the day the car laps consistent times on a road course or a drag strip... Who really knows how much one or four hundred horses can pull anyway.... Its all about having a good time

Hey Ryan
IMHO, JE's Dyno is somewhat optimistic. This has been proven to me by posts from a number of other posters. However, your numbers do seem on the low side for the second portable dyno. I believe you should be putting out between 390 to 400 horses to the rear wheels with your setup. I also believe the Dynojet dyno to be the most consistent and reliable dynamometer for measuring wheel HP and air to fuel ratios. Now guys, this is just my opinion. No flames please.

A low 60' is all driver. High trap is all horsepower. Back in the days when tuning fuel with jets in carburetors, we tuned for best trap on the main jet. With my old FJ1100 there was a 2 mph penalty for one size rich or one size lean, but it was very consistent on trap speed even when I wasn't the best off the line.
Besides, there are a lot of things a dyno can't do or show that make all the difference in service. Anyone claiming they can tune part throttle on a Dynojet is just flat lying.
I ran my Supra on a Dynodynamics unit. It showed about the same as a Dynojet, but the weather conditions, altitude, and fuel were all different, so I just looked at the numbers for giggles and decided it runs just fine...
