Well. Each time I drive it does not rave past 2500rpm. I tested the MAF sensor it seems fine. I removed to check if the DPF was blocked and it's not because the car seems was already deCATed (there's no DPF/Catalytic Converter). When I am at 2500rpm it just comes to a halt. As if I am slamming on emergency brakes..
Car now ok. Turns out to be a Boost Leak at Pipe from intercooler to intake. FIBRE glassed the area and now car has gained a tremendous amount of power.
