Thats odd, your spiking to 18psi with Hypertech? I never noticed a spike with mine, maybe I should check to see what I'm actually boosting now, the damn thing pulls like a mother no time to look, just trying to white knuckle the beast.
Would like to get the PG kit but need Ken to PM me back. :/
Mine was to be here this past weekend, Told me the cores where not ready yet...
Still waiting.
I have been waiting for almost a month now... hopefully it will be all over by tomorrow.
or if you want a even cheaper one, you could do with the altered customs one.
