I have recently changed my remote waste gate, the waste gate was controlled by air injectors. I have switched from a RS200 original waste gate to a Progate 50.

My question is this;

If i do not achieve the same boost as i did before (i dont expect to as the progate is larger) can i increase the spring rating in the waste gate to try and compensate?

I would have liked to have had the air injectors mapped with the new waste gate but it is hard now as the company i used and trusted to map my home built engines several times have shut down.

Also, would there be any adverse affects changing springs i.e would the waste gate try to lift earlier than it may have before as the engine was trying to reach maximum boost?

If there is any mapping experts reading this your thoughts would be appreciated,

Thankyou
