What is the best ecu to run when you want to get 300 rwhp on stock internals?

[Machari]

I was wondering what would be the best upgraded ECU I should run or if I should run an upgraded ecu at. I have seen cars with the Apexi Neo along with the JWT(Jim Wolf Tech. ECU) get 300 whp. I was wondering can this be done with just the Apexi or would it require and upgraded ECU as well? I have a 1990 240sx fast back with a KA24DET, with FMIC Walbaro 255,450cc injectors. I am running a t3/t4 turbo.Stock internals of course...? I have not dyno'd mi car but im sure im not over 300 bcuz Im just barely hanging with 350z's.

Are you trying to get 300 whp on a stock KA24DE with just an ecu upgrade?If so pinch yourself because you are dreaming.

Do us a favor and specify the model, year and what motor is installed.

We're not mind readers!!!

So you have this stuff on your car and you are driving it but you have no fuel management? I would call BS but i have seen people do stupid **** like this before and the car somehow still drove. You need a reflashed ECU or GReddy E-manage or something.
