Max Power From 50trim

[BlackHawkAWD91]

I was wondering when you would be doing more harm then good with a 50trim. At 21 PSI the car traps 90-91 in 1/8, at 25psi, car run mid 97s mph. Is there more power to be made in the 28 - 30 PSI area or is this to high?

Thanks

It can handle 30psi just fine.
