    I have a problem with tip-in det. and detonation at high rpm's. I am getting 10.5psi at 8k rpm. I have a Cartech 2005 FMU. I'm getting enough fuel under full boost, but my MSD BTC doesn't seem to be working well at those boost levels. I can hear a slight detonation coming in and out after 6500 rpm. As far as tip in I think the base pressure is set at 55psi atmospheric. Should I rase this?

    I highly recommend picking up a JR MAP controller if you don't already have one. By the way, what pulley are you running on your JRSC kit? The stock one?

    ehich pulley do you have installed? I assume not the stock 6 psi pulley. You might try raising the static fuel pressure up to 58-60 and see if this helps. You will lose a little power, but hopefully it will stop the detonation. Also if you are purposefully running that high of psi you may want to get some larger injectors.
