Right now the car hits 7psi at around 3100rpm and slowly climbs to 13.x psi. The wastegate opens fully around 7-9psi. If I incorporate a MBC to have the wastegate open at 12psi will that likely shoot my overboosting up as well? Or because its already over the psi that flapper opens fully it will make no difference aside from aid in spool? I guess I can throw one on and test but if there are any theories I am glad to hear them. I will post a before and after here and maybe in the spool data thread.

7psi Wastegate only spool data:

2000rpm > 0.2psi
2500rpm > 4psi
3000rpm > 6.7psi
3500rpm > 7psi
4000rpm > 7.5psi
4500rpm > 8.2psi
5000rpm > 9psi
5500rpm > 9.4psi
6000rpm > 10psi
6500rpm > 13.8psi
7000rpm > 12.3psi

it should work ,but reality often differs from theory

Ended with this data. Kept the car on the 12 clicks setting but might revert back to wastegate only for safetly.

It seemed like upping the mbc would add to the mid range boost numbers but was slowly spiking peak boost as well. I wanted to get a flatter boost curve but I don't think its possible without the peak boost rising.

EBC is a better way to go.
