Hey I have the efini kit on my car with beat down pipe 850 cc injectors 3mm apex seals and big front mount. It has aem ems also. There has been some pretty agressive port work done. I bought the car this way and it needs tuned but i dont know what to expect. What kind of power should i look for?

turns out the aem is bad. He told me that he has a stock ecu with an Eprom flash? Will this work?

as long as you run no more than 10psi of boost, i think stock ECU might be okay.

well the boost gauge says its making 15. It does start to cut boost in 4 gear though. I am working on getting a power fc right now.

just be careful running 15psi on a reflash ecu. there's no telling what the timing map looks like at that boost level.
