94 KZN 130 boost

[budweiser]

Hello you all, hoping that you all are keeping well,
got a 1994 KZN 130 surf that I had done the following:
Egr delete,
New injectors,
3 inch exhaust from turbo,
turbo washer on wastegate
Intercooler,
Resistors mod,
New head,
And many other things;
Now when I'm driving it, it drives well, till when I accelerate to overtake someone, it bogs down as if the fuel cuts off,
I know fuel cuts off about 14 PSI, is it any simple way to make think the computer that is ok to not cut the fuel, counting that is only that is the problem.
Can you show me some light on this? Many thanks

Check the throttle position sensor and the ECU. Either or both could be on the way out, or not talking to each other. I had the same thing happen to mine and ended up getting the ECU rebuilt and replacing the TPS.

Got a spare ECU, makes no difference, don't have a spare TPS to quickly check
