Other mods previously installed or installed along with the kit and built block:
JWT Springs and C2 Cams
HKS Headgaskets
ARP L19 Head Studs
Samco Hoses
Nissan Rear Cooling Mod
KOYO Slim Radiator
JWT Flywheel
Clutchmaster FX400 CLutch
TurboXS Utec and Tuner Pro
Sertrab Oil Cooler
APS 3" Exhaust
AAM Plenum Spacer
The car was tuned for base boost of the wastgates which turned out to be 12 psi, we will tune for higher boost later. Results on our Mustang dyno were RWHP=476 and RWTQ=411, he took it to a Dynojet and got RWHP=507 and RWTQ=442. I am sure he has his hands full with that but will bring it back in for a higher psi tune.

Turned up the boost this weekend.
We got 550+ HP and 530+ TQ on 18 psi. When adding 50% race fuel we were able to get 20+ HP out of her. This was done in forth on a Mustang Dyno in 78 degree weather.
Thinking something is holding her back.
Took her to the track also and my poor skillz only got me a 12.9 at 124mph.
I didnt hook up till 3rd. 1/8 was like 8.9
I need lotz of practice.
I have to say this has been a great experince and want to send out a BIG THANKS to Gus and ROGER at Japtrixs!
Anyone know any respectable DynoJets in the Broward/WestPlam area?

Yea thats why we didnt go higher, we did one run with 20 psi but didnt see a difference. We were in the 540-550s all day on pump gas even at lower boost, but with the 2+ hours of tuning I didnt want to say 15 and it was actually 17. I remembered getting like 557 on 18 psi so I went with that one.
Our next step is to find out was the car getting heat soaked, hit the limit of the heads, or is it something else I over looked.
Also remember these #s are on a mustang dyno which ppl say could be around 10% lower and done in fourth. On my car I have seen as much as a 15 hp lower in fourth, opposed to fifth. But every dyno is different so I'm gonna wait to see if we can find the limiting factor before taking her to a dynojet again.
Dont get me wrong, I love these numbers. I also expected more from that PSI level. But if it wasnt a challenge, it wouldnt be that much fun.

Well there are a lot of other factors that come into play not just what the turbos can or are capable of doing just look at the single turbo kits.
We need to look at other things and mainly air flow, the heads are basically stock heads, it has the stock 287 HP lower plenum and an AAM spacer, maybe a 300HP lower plenum with an APS upper plenum will help maximize the airflow through the plenum and into the runners without going to a plenum like the SFR plenum which flows right into the runners.
Also looking at port and polish of the heads, as well as oversized valves and a 3 angle cut on the valves.
When you get to this level trying to get the most out of a kit you have to look at all of the little details and decide how far you want to go and how much to spend it is not just sticking big turbos on.

I wish there was a try then buy policy on some high quality heads...
Gus we need to go out for dinner with Roger and figure this puppy out!
*Traction*
I think my Fat AZZ solved the problem for the time being. (w/ DRs)
Next Im gonna need slicks to dyno her.
