What car are you talking about? I haven't messed with anyones motors/tuning in a long long time.
I only build my friends motors and I do that for free.

frist. the dyno we were putting out extremely low #'s. According to the owner of the dyno, he said that he has the tech came to his shop to figure out why it was doing it. Basically, the tech couldn't figure it out but they estimated that the % is around 5% lower than their other dynos. when compared to dynojet #'s, you're looking at 20% lower #'s.
Lupe's car was the first on the dyno. The most we managed was 445rwhp@23psi. with the 20% estimate, it made 533rwhp when compared to the dynojet. The car was running 950cc/1300cc injectors with 50psi base fuel pressure, C16 fuel and 80% duty cycle. a/f ratio was around 11.5-11.6
The very next car was a street ported engine with stock turbos. We made 252rwhp@13psi. with the 20% estimate, it made 302rwhp. That sounds about right with the mods he has and the map I was using as a base line. a/f was around 10.9-11.0
next was another stock turbo with stock ports. It made 230rwhp@13psi which translate to 275rwhp. (sounds about right since he has a high flow cat). a/f was around 10.9-11.0
next was a car with the GT35R turbo and a ported engine. The car made 322rwhp@15psi. with the 20% estimate, it made 386rwhp. I think this is the car that I feel has a restrictive exhaust system. (can't remember). a/f was around 10.9-11.0
next was a TII with Davichi turbo and haltech. The car made 355rwhp@15psi. This translate to around 426rwhp on dynojet. The duty cycle was around 82% with the base pressure of 45psi running 550cc/1600cc. a/f was around 10.6-10.9 (i tuned it richer since I thought it was making a little too much hp).
Those were the cars that was tuned on the dyno. I did the rest on the street since the dyno place was closed on sunday.
Now, its hard to say if the 20% estimate is accurate or not but based on the other three cars in the middle, it seems about right. The only way to verify it is to goto a dynojet or run some 1/4 to back up the hp claims.
Only time will tell.

Goodness, this thread got silly in a hurry. I just read all of these posts.
For the people who contest the figures -- don't worry -- the cars will either stand on their own at the track or they won't. That's what it all boils down to -- consistency in the trap speeds that correspond with the aforementioned power levels. Although I am a competitor of Steve's, if he says the car made 530rwhp, then I would tend towards believing him more than those of you guys out there that have never done this kind of work. I respectfully suggest that those of you, that are sitting at your computers, who've never really spent the hours, days, weeks, months, and years it takes to earn this kind of skill, be a bit more considerate on whether or not your assumptions might indeed be wrong.

What matters is the trap/time not the freaking dyno.

It's quite funny on here at times. People post their dyno figures if the numbers are low they get bashed & if the number are high they get bashed. lol
Look at his setup and you will see that 533rwhp is more than achievable.
Lupe how much did it cost to get the ford rear-end + fitting etc ?

actually, the numbers should be 20rwhp under-rated. The owner of the dyno told us to add another 20rwhp on top of the 20%. I thought it was kinda weird so I just stick to the 20% after the 2nd and 3rd car got tuned since those cars seems to match up to the 20% using the map I had.
