R33 rb25det s1 FMIC problem

Hi guys 

 

R33 rb25det s1

I just changed my intercooler from a 580x28×68 not sure on brand as i got it with car to a HDI gt2 600x300x80 and went back for tune and lost 400rpm in response/full boost

Power with before intercooler was 341rwk and power with hdi gt2 intercooler made 360rwk 

Before would hit 20psi at 3800 rpm now 4200rpm with just intercooler swap nothing else no piping changed nothing/still same length and size

(Hypergear gear ss2/external gate/e85)

 

Boost level on before intercooler was 20.5psi and boost on intercooler hdi gt2 22psi 

Would see Full boost in first gear with before intercooler and now cant even make more then 12-13 psi in first on hdi gt2 

Could it be the intercooler to big or just cheap chinese intercooler compared to before 

Any help would be great

    • Price seems pretty good to me. Also seems a hell of a lot cheaper then buying another vehicle that only ever gets used for towing.  I'm a long way from you mate, I'm a couple of hours out of Brizzy. 
    • New [400]Z, they're available in manual and you don't have to worry about parts scarcity. 
    • Just planning to have the wiring neat and hide as much as possible.
    • The sodium acetate, mixed with citric acid, doesn't actually buffer each other. Interestingly though, if you used Sodium Acetate, and acetic acid, THAT becomes a buffer solution. Additionally, a weak acid that can attack a metal, is still a weak acid that can attack a metal. If you don't neutralise it, and wash it off, it's going to be able to keep attacking. It works the same way when battery acid dries, get that stuff somewhere, and then it gets wet, and off it goes again breaking things down. There's a reason why people prefer a weak acid, and it's because they want TIME to be able to be on their side. IE, DIY guys are happy to leave some mild steel in vinegar for 24 hours to get mill scale off. However, if you want to do it chemically in industry, you grab the muriatic acid. If you want to do it quicker at home, go for the acetic acid if you don't want muriatic around. At the end of the day, look at the above thumbnail, as it proves what I said in the earlier post, you can clean that fuel tank up all you want with the solution, but the rust that has now been removed was once the metal of the fuel tank. So how thin in spots is your fuel tank getting? If the magazine on the left, is the actual same magazine as on the right, you'll notice it even introduces more holes... Well, rust removal in general actually does that. The fuel tank isn't very thick. So, I'll state again, look to replace the tank, replace the fuel hanger, and pump, work out how the rust and shit is making it past the fuel filter, and getting into the injectors. That is the real problem. If the fuel filter were doing its job, the injectors wouldn't be blocked.
    • Despite having minimal clothing because of the hot weather right now, I did have rubber gloves and safety glasses on just in-case for most of the time. Yes, I was scrubbing with my gloves on before, but brushing with a brush removes the remaining rust. To neutralize, I was thinking distilled water and baking soda, or do you think that would be overkill?
