Well, if your gauge is reading 12psi then he might have just turned up the boost to do a pull and then dropped the psi back down to 12. You should be safe at 12. I am going to be installing a boost controller tomorrow so turn up the boost from 10 to 12psi. Ill dyno it on the same day as you at 12psi and we can compare numbers.

Some insight on dynos and my thoughts..
Every dyno reads different! They say that dyno dynamics, dyno paks, Mustang read lower than the popular shop standard Dyno jet. Ive heard people say anywhere from 10-25% lower. Its all "hear say", there is no proven formula to compare different dynos. I know in Japan dynapaks are standard. my personal favorite dyno is the dynapak for its accuracy and precision in tuning.
Ive seen alot of people compare their hp online, and honestly its not accurate. A few factors to consider include the make/model dyno, settings in dyno, calibration of dyno, air temp, altitude, moisture,time of day, spark plugs, fuel, etc.
My honest opinion is that a dyno is a tuning tool to tune your ecu, and maximize your vehicles performance! When tuning your vehicle, continue to stay on the same dyno, at the same shop to help keep track of your mods and vehicles hp progression.
Another thing is its easy to crank up the boost +15psi on stock twins and laydown a big number, but how long are those turbos going to last? Or maybe crank its up for one pull for that nice dyno sheet to frame on the wall
haha
If you want to compare hp acurately, it has to be on the same dyno, and same day/weather conditions. Theres alot of factors..
Use the dyno to measure personal gain on your vehicle..

i agree, but i'm not sure about the dynapack dynos. i'm skeptical because the last one i used i turned out 485whp on a GT35R FD at 18psi. maybe i'm that good, maybe the dyno reads higher than the dynojet i usually use, only way to tell would be to do a run of the same car on each i guess.

Of course, you always want that one dyno sheet that you can frame lol

the dynos seem close but i haven't really noticed that it was far out of line with the dynojet, if anything they were very close with the dynapack possibly reading slightly higher.
in the end it's always about the calibration of the dyno, some of the engineers/installers that set them up don't put in the proper calibrations which is where a lot of these variations come in.

Hey guys. I have been MIA due to work. Here is the new plan.
1. I bought new injectors and I will be changing out the primaries to 850cc
2. I bought a greddy boost controller and will have the car street tuned up to 14psi. I will most likely only run the car to 12psi most of the time but just for those moments where i want a little more power, I will have the option to crank it to 14psi.
3. I will most likely not have the car tuned on the dyno this time. Unless someone has a dyno I can use to make one run to see how much power it will be putting out lol

Well, after doing a lot of reading and from the responses from the guys on this thread, it really comes down to running the car on another dyno to compare the numbers. I am not sure if I want to do that and put my car through that abuse again so I think I will be happy with a street tune for now. The car is already tuned to 12psi so all the tuner said he needs to do is add more fuel and mess around with a few things to get it boosting at 14psi safely.
Here are the mods on the car:
Non-Seq conversion
Peter Farrell intercooler
Fluidyne radiator
downpipe, midepipe, rb catback
New injectors (primary and secondary 850cc)
Fuel pump upgraded to supra denso pump
30k mile stock turbos
Greddy boost controller
Power FC
Suspension: R&R springs on tokico shocks
Interior: stereo head unit is removed to reduce weight hahahaha (this is my most important mod. I actually bought it that way)

Forgot to mention previous owner claim that Steve K tuned it to 290 (I assume it's WHP)
Apex-i PowerFC with Commander
Apex-i AVC-4 Boost Controller
HKS Twin Power ignition

Also, it has to do a lot with your engine condition. Was if just rebuilt, or does it have a lot of miles on it?

Engine have about 20k miles on it. It was replaced at 65k miles with Mazda Manufactured engine. Car only leaves the garage for track days so I barely put maybe 1000 miles on it a year. I guess I'll run a couple track days and see how it feels.

street tuning is actually more abusive than a dyno tune is since the car can rest easier after a pull which puts less stress on it, it's all just crammed into a smaller timeframe though.
i prefer street tuning since it is the most accurate method of tuning but it is less safe due to driver focus and high speeds which always add a chance of something going very wrong and can take quite a bit longer depending on your surroundings.
if it's my own car i do street tuning only, if it's a customers car i will do dyno only because it's cheaper for them(just driving to a tuning section of road can take 45 minutes each way plus hours of actual power tuning, plus the added cost of the liability of getting an expensive ticket or thrown in jail). if they want the best economy and power mixed then it gets dyno tuned followed by a normal driving street tune(for those who want 20+mpg).
i don't do power street tunes anymore just because it takes 1/3-1/2 a day and has other liability factors.
