I do recommend programmable EFI injection system and wasted spark.
Ke-jetronic ignition controlling arent sharp enough when pushing more power out of the engine and fuel managment is bit rough. I think ke-jet was invented in 70īs..

my ex rst has 180ps with ke-jetronic and it everytime dropped little lean when pushing hard and only 10psi of boost. This way i destroyed more than 2 engines, 4 conrods and 4 pistons.
Then i get programmable efi and after then there is no need to open engine any more.
And this only when some professional has been mapping the controller with wideband afr system.
Now i have "new" hobby car.. RST naturally and i megasquirt & wasted spark system installed waiting for proper intercooler & new better injectors and then proper mapping for EFI.
