18 psi with the stock turbo is too much boost. At that level, it will be pumping a lot of really hot air. This isn't what's causing your stalling problem, though. Drop the boost and try putting on the stock intake and see if the car runs any better. Have someone professionally tune your car to match your big injectors.

It's your injectors, and your intake isn't helping either. It's absolutely impossible to outrun the stock injectors on the stock turbo without nitrous or alcohol injection. Put those two items back to stock and go to the appropriate base map (stage 2 TXS I think) and I am 99% sure that will solve your problems.
And yes, 18 psi is too much. Tune for 16 psi. If you tune right your car will be faster than before, even with stock injectors.
