RB30 Fullrace EFR7163 Max hp on pump gas 97

[Nur spec]

Cant find much info about EFR7163 on here.
So i decide to make a thread.

Currently my car set up is full build OS Giken RB31 with Naprec head build , upgrade fuel parts, with FullRace EFR7163, with PFC D jetro.
Yesterday is my car tuning day, When first 1.2 bar it just get around 640whp. until 1.6 bar it just 694whp. I am abit dissapointed with the results. We try to get more boost, but seems like the MAP Sensor cant handle more boost than 1.6 bar, need to switch to bigger map sensor maybe 3bar or 5bar. We guess 2bar which is max boost for this turbo.

My Question is, How many whp can this turbo get ? Its run with RON 97.
Starting my target is around 800whp - 850whp. But now seems like a bit hard, as reach 1.6bar still just 694whp. Fullrace did tell me this kits can make 800whp-850whp. But i dont know what is the problem cause. Fuel supply is still very enough.

Is my ECU Too old for this ?

Thanks Guys.

Your old ECU should be fine. You definitely need a better MAP sensor and after that your tuner should be able to spot any roadblocks. You say your fuel system is fine so have you got at least a 3.5in exhaust (4in better) and have you upgraded your ignition system? What is your engine revving to? Can you post up some dyno charts?

BTW 694 (is that 4 wheel hp?) is not too shabby.

Especially since a quick look online suggests they are only good for 550HP??!

OK the twin scroll 400 - 600 hp?!

Thanks for reply.

What else brand map sensor is available in market which is suitablr for pfc d jetro? Because i found the one apexi map sensor is 3bar. I have okada coil plasma for ignition, yes, 3.5 inch exhaust. 694whp is for twin 7163 on rear wheel. Yeah, i saw online the turbo is rated that. Thats why i am a bit dissapointed i cant get what i target. Lol...

1. New ECU (comes with 3/5 bar MAP sensor) with Ethanol sensor. 

2. Compare US dyno figures to Aus.
