Wow, when we pressure tested mine the cat was a restriction at 384, tunehouse dump into the same system as yours. The guy I bought it off found it to be a restriction at the same power.

Both on 98 at around 19psi

Manta twin 3"

With plaz cooler + plenum+ intake

Ported turbo + actuator

Valve springs

Surge+ 044 + 60s.

Twin 3"

407rwkw at heaps of boost. Think 360 at 16psi iirc

If I could get 360rwkw I would be happy but I doubt I could as my exhaust sounds like it's a big

Restriction after reading the sizes you fella's run.

378 at 17psi? And I made 370 through a twin 2.5 without the planum and hotside piping

Comes down to the tuner I guess because I have far less pipe work for the air to go through before it reaches the throttle body there for it should be colder and make more power.

Mine made 370 at around 16-17psi on 98 ron with a PW stage 2, walbro intank, seimens dekkas, xforce 4inch dump 5 inch cat and twin 2.5 cat back.

Don't worry about dyno numbers mate, there are so many variables.

The blacktop is the true indicator of power, for referance mine went 126MPH with 370rwkw on 98.

Did they say what was holding it back

I spoke to the owner of Real dyno and he said for the mods to the power it's about right .

But he would go single 3.5" exhaust and 100cc injectors .

might be the exhaust holding it back.
