Well Ive searched and found some help.

I just chipped my car today and its GREAT, brand new upsolute program, pretty amazing software!

I peak at about 19-20psi the guy told me it would peak around 17psi.

Im getting some slight hesitation when hitting it to WOT and when it goes to 20psi almost like a surge.

I have replaced my diverter valve with an adjustable aftermarket one, do you think i have to adjust it?

The guy at upsolute told me my n75 might not be working properly and spiking to 20psi.

Also when driving it will stay around 17 psi but then occasionally to 20psi.

Im really thinking n75 valve, any advice? (btw i want to keep it at 17-19psi)

 

Its pretty normal for boostto peak/spike and then level off/hold a few psi bellow that. Dont adjust your dv, make sure its recirculating all boost back into the intake. A different N75 valve, like an H or a J version would help eliminate spikes and surging.
