Gotcha on the full control.
Lets say: Block stock rods and crank, aftermarket pistons and rings
Cam stage 2, upgraded valve springs, but stock valves, shims, retainers, adjustable cam gears
FFIM with bigger throttlebody, exhaust header (tube) and bigger better flowing exhaust and bigger turbo elbow but stock turbo
bigger injectors 550 and better fuel pump and FPR
Anyways a mild built street car may see the track once a while.
Will the stock ECU be able to handle these type of MODS
I understand a standalone you have full control over all the engine functions and can see what everything (sensors) are doing in and one the engine.
Question: Is the stock ECU able to handle these MODS?
