R33GTST Intercooler problem

[RamR33]

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 

 

Sorry wrong thread

Extra 20KW would suggest its a better intercooler. How much time was spent on the tune? It would be quite different with that much more air.

Don't think you would want full boost in 1st.

I had similar issues when I had a front end smash and put a cheap fmic on until I could afford to go back to the blitz fmic I had previously before the accident 

long story short after a dyno run I went and got the blitz one straight away because the cheapy was not doing me any favours whatsoever
