personally I would go with the hp and have the extra room to grow... otherwise either pump should be a-ok for your setup.

I use the LP w/ DSM 450's - you shouldn't need to run higher than stock fuel pressures with that setup.

You may have idling issues if you use the HP due to too much fuel pressure with the stock FPR.
