last night put on the 034 turbo inlet pipe and forge mbc and have the 15 psi spring in and its spiking at 26psi and settling at 20psi and i have it set for 15?!? also when it stays over 20psi it starts poping out the exhust is that a resault of the spiking? its speedtuning stg2 so its tuned for 18psi.
