well
on dynojet, 200hp, 278nm and i called it a day, still messing around with various maf clamp because it still boost cut @ 5500rpm now.
original hp on dynojet is 150hp and 230nm
P/S : My ignition timing is still a -4degree :P , wait till i move it up, also boost @ 0.3bar, wait till i move it to 0.5~0.6 bar :P

good news guys
i found the clamp voltages and i max'ed out my injectors as well
at 0.25 boost, turbo start spooling around 2000 rpm and full boost 3100rpm at 0.25 bar, 210hp/300nm now, after i drop the engine a 2nd time to block the exhaust valve that recirculate air into the intake manifold.
getting injectors now and pushing it up all the way to 0.5 bar.

i would say about 50hp but 80~90nm .. with max'ed out injectors, i don't really know if this is the max i could go, i would say more. there is not enough fuel flow above 4500rpm ... it leanes out.
the turbo is sized correctly, and its a ball bearing, which spools and goes into full boost fast enough.
this 2 turbo can make 560hp at least @ 1.1~1.2bar, so by going 0.5~0.6, i would say 250hp ? maybe more ? but there would be load of torques

wait :P
even the dyno chart is not nice now as it leanes out above 4800~5000rpm
let me finish changing the injectors, pushing it more, then post a final dyno here, as for the car
its parked in the workshop for 1 year , nearly 1 year on this project ... so now its done, full of scratches, minor dents and so on, let me repaint it :P

Dear Friends
Project completed, @ 0.6bar, 290hp, 388nm , i am so supprise in the torque, but here u guys go, i am running 0.43bar @ 43kpa now and this are the results
i will do another run with dynojet tommorow and bare in mind, this dyno has lower power then dynojet :P
using 260cc injectors now which i took out from a nissan fairlady 350z :P
duty cycle @ 90%
lowered hp due to stock internals, better be safe then sorry

Great job. Glad to see it come to completion. 
Ya should create your own thread to summarize the whole process in a few posts so future readers dont have to go through 13+ pages to find all the info

Updates..
0.6bar @ 60kpa @ 296rwhp , 413nm torque / 365engine horsepower , 490nm engine torque. gearbox is going to MKB germany for the 700nm torque upgrade and tcu reprogram unless of course, if i manage to find a c32 engine with gearbox, then its a different story.
what did i change to the engine for more power ? <-- there is a variable flap in the N/A intake manifold that open progressively as the rpm goes higher, i cut the flap off so now the flow can be better, earlier the turbo full boost at 3100rpm, now it does at 2200+-.
as for the engine, i am maintaining the 2.6l , crankshaft looks strong enough , Custom H-Beam Rods, forged piston with 9:1 compression, custom bearings and so on, i will also look for someone with the capability to tune the original ecu to remove rev limiters for me, i will be spinning the engine to 7000rpm now. as 2.6l has big bore and short stroke, the rev could be higher, custom head gasket will be made now.

In other words are you saying you removed the EGR valve(exhaust gas return). I've wanted to do that to my M113 for some time now and TVT here even makes a block off plate for the M112/M113 EGR vavle. My concern is the ECU mapping and how it responds to just blocking it off....??

i mean the variable flap in the intake manifold, if u take out the intake, u will see there is a flap, i cut the flap off so the engine is full time receiving full intake air
i also get a CEL error B28 Pressure sensor whenever my car goes into boost, after checking, there is a map sensor and that map sensor controls the opening of the variable flap, what i did is clamp the voltages, its 3.78volt at 100kpa above atmospheric level = i remap the voltages so it will not go above 3.85v and hence now the cel is gone.
I believe if i have a C32 Engine i may be making 500hp already with this 2 turbos, they are my own spec turbo, AR .64 rear housing, GT2530 front housing machined to hold GT2871R fins.
I need fellow friends help now, my car is a right hand drive E240, with the current power, it wheelspins whenever i floor the car suddenly. i need a LSD, and quaife don't know if they have applications for me .. Anyone can help me find out if any quaife application can fit my car ?
My vin numbers starts with WDB2110612Axxxxx if i am not mistaken. can't remember the last 5

well i learned this from the kleemann supercharger kit where they removed the intake totally and just blow air in.
i will post new dyno graph, i was thinking if i get this engine's rev to 7000, it should make petty good power the 2.6l is big bore short stroke, hence the capability of higher rpm, from the dyno graph, the power still hasn't drop at highrpm. the only thing why it drops is cause i retard igniton timing and trim boost, as the gearbox can't take it.
