E manage have different products for different car’s, designed for the stock map sensor.
The stock Honda map sensor a 2.2V sensor can only read 11psi, factor into the fact you don’t’ want to max out your sensor a safe level is 9psi or so that you can accurately read.
So that’s where e manage limits lie, and due to the fact you can’t configure it for a different voltage map sensor such as the 3 or 4bar motec map sensor that many ecu’s use. And trust me you don’t want to push the limits of the stock map sensor !!

Not many kits actually provide ecu based computers with there kits FMU’s and FPR’s MSD ignition retard etc change the final output directly to the engine they don’t fool the ecu into thinking / reading a different valve so these devices do work completely different, so that’s why these devices re fine.
As for buying a turbo kit why don’t you make up your own !! trust me it’s a much better option than using any kit !! always resulting in a higher quality reliable product, every kit cuts some corner !!!!
At the end of the day all you need is a very strong turbo manifold, a nice turbo, oil feed lines, a intercooler and exhaust modified and some cooler pipes, 4 larger injectors, a nice fuel regulator to make sure fuel is flowing nicely, nice intake fuel pump and some decent engine management which will handle anything you though at it, why do things twice do it correctly the first time
