Looks like he made 264.6hp. There is yellow line above green.

On air regulator valve, you can not use air filter, it will leak boost. On AAC, i am not sure if it can close air tight. You can try blow air to see if it seals.

Is the power-fc D-jetro or L-jetro? With L-jetro power-fc, it does not see boost so it's only controlled by set duty.(can hook up map sensor to see boost). D-jetro can actually control and learn solenoid duty. Greddy solenoid and Apex solenoid looks identical to me. But if you already have boost controller just use what you have, because sometime power-fc learning boost duty became headache. Meth on stock turbo?....not much gain.

The Power-FC base map is for Japanese 100 oct, usually timing is too aggressive for 91oct. If you have connected the check engine light you can see when it knocks. I would recommend running on stock ecu to tuner. For tuning Power-FC i recommend koji at Driftspeed in Los Alamitos. He is the Power-FC tuner from 90's.

If disconnecting solenoid works,that means dip switch is set on external W/g. External W/G has two ports, top and bottom. You are probably using only bottom port. So, boost controller has dip switch to change from internal W/G to external W/g. You are using external W/G like internal, which is ok but boost controller dip switch should be set to internal W/G. Maybe you had it hosed like external W/g before rebuild?

Is it internal or external W/g? Did you try disconnecting solenoid wires and run?(not just unit off, but solenoid box wire completely disconnected) If you have it hooked up like external W/g with two hose, blowing through is going raise boost. Just curiosity, how is the tune with ITB turbo? Are you using MAF? What ECU? how is part throttle run? ITB turbo usually needs advance tune...

The one with three row and white is for RB25det(ER34). That's not gonna work.

The white ecu plug is for r34 GTR. I think R32 and R33 has blue connector.

oh.. easiest way is to use R34 harness and R33 or R32 ecu and just flip the CAS(crank angle sensor) signal wires. CAS has 4 wires, power, ground, two signal wires. JUST flip signal wires at ecu or at sensor.

Well first thing .. you can not use R34 RB26 ecu on S30....... It has immobilizer. You will need to use R33 or R32 ecu and harness. Cas on R34 is same as R33,32 I think it just pinned backward. check service manual online. R34 has no ignitor, it's in the coil, so all you need is skip the ignitor and go straight to coil.(signal wire) Dwell is same as R32 R33 so it will work. I would use R33,32 Apex power-fc so i can see all the sensors and can be tuned for optimum.

Hks ssq bov has very small barb, make sure your hose is reduce to correct size. And hose should have good vacuum at idle, unless you have big cam.

To run on low 12's, you should be on race gas at 18psi.

first thing is to find out is it ignition or fuel problem. Most likely fuel problem by hearing the engine sound. Now is it too rich or too lean, most likely too lean if it's ok when cold. To find out just pinch the fuel return line with plier to increase the fuel pressure while engine is running, if it gets better it's too lean ,worse too rich. So now you can narrow down the problem. On Rb26 fuel is added or measured by maf,tps,coolant tempsensor,intake air temp sensor. Maf do most. make sure you don't have the rom tuned ecu that has Z32 maf calibration. if you have friend with Rb26 Power Fc You can use commender to see which sensors are bad.
