    Hi everybody. Installed the flowmaster delta boost module. It makes a big difference. Wanted to point out it's half the price of other piggyback modules but only falls shoet maybe a few ftlbs of torque and hp of others. I can get you 10 % of if you order from Walmart. ordered a knockoff gfb dv+. Already have the name brand just wondering what the difference is. I'll let you guys know that also. Contact me if you need 10% off at Walmart. Com

    Just realized either Autocorrect on my phone or I had a du huh moment and didn't put flowmaster in the thread topic, which was the whole point. Can a mod fix that?

    I've been messing with this flowmaster module for a week or so and I've noticed some issues with my manifold pressure. I didn't use a boost gauge before putting this in. What I've noticed is the pressure swings quite a bit. I felt like the power delivery was choppy before the module and the gauge showed the boost pressure to be the reason. I removed the OE diverter valve and it moved freely but sounded like there was grit or sand between the thin metal plunger and body so cleaned it up. That really didn't do much if anything. From what I've been reading seems like the gfb dv is a must have so got that installed and it did help some. I also put slightly more tension on my wategate. What I'm seeing is the pressure jumping to 24 psi when I floor it in 3rd or 4th then it may drop 8 then bounce back to 12 - 18. It's just erratic. Those numbers are with the boost module on but are all reduced about 3 psi with the module off with the same behavior. I haven't done a leak test or watched what the boost solenoid is doing with and obd scanner but thought maybe this is to be expected. I can't find anything looking through the forums other than some Fiats having power dips around 3k rpms. I don't see that in any Dyno sheets I've seen for darts though. Maybe you guys could point me to specifics threads that discuss this. Thanks
