I'm looking at the special that Bean might do for the DIY Stealth pump. My question is Bean said it comes with one IPR or a second IPR can be bought and added to it. Whats the purpose for 2 IPR's?
I do not think the DIY Stealth is available at this time. I think it is superceded by the new pump.
2002 F350 Lariat CC 4x4 4.10 DRW, with "the ultimate towing setup!": Nov 30, 1999 engine with Fluidampr, Melling LPOP, 910 springs and ARP headstuds, DP-Tuner, DI regulated return, AC singles with 80% over EDM nozzles, BTS dual HPOP, H2e, Spearco 6.0 IC and BTS tranny .
Without getting into the oil wars.... The dual IPR option allows the pumps to work without any kind of special tuning. With a single IPR some trucks stumble a bit on decel without tuning specific to a dual pump single IPR setup. When my pulling truck was a DD running off the shelf tunes it had that issue, and I never really addressed it with my tuner. When I did the motor work I added the second IPR (because I think it makes sense......) and it ran fine with no issues, same tuning as before.
