Isnt there a way to rewrite the ecu so it doesnt speed cut at 120mph??

[eh?]

For the RB25 cut Ecu wire # 53.

[lilskyline240]

that will get rid of speed cut?

[eh?]

yes

sounds like you also have boost leak if you are seeing 5psi at 5krpm.

i dont have my motor in yet...but i heard that the ecu only lets u boost to 5psi under 4500rpm
