aiyo lazy la bro to calculate calculate

i show u wht i have already calculated for my car hehehe

1.7bar Boost

AEM Methanol Injection with 315CC nozzle
50trim T04E turbo (small turbo only mar)
output will be around ~400hp
but of cos , many more variables which I dont have knowledge of on the calculator
