I have a question about the turbo limit.

First off all, I have a Escort RS turbo 1987 S2, (without knock sensor)Forge actuator with yellow spring and ECU hearts - diamonds - hash tag.
The turbo runs at 0,9 bar or 13 psi max and in the second gear the turbo limit and the tour limiter are at the same time.
Only when I go the 3th,4th or 5th gear the turbo limit is earlier at the end then the tour limiter.

Is this normal? Or what do I need to do? to get the turbo limit at the same time at the end of tour limiter.

(If I play with the gas and watch out that the turbo doesn't come above the 13 psi the car runs till the end of the tour limiter.)
