Who has any Real first hand experience with The RCD Thumper 1 Hpop? I put mine in about a week ago and it will only run 3.5-3.8v on a wot run my stock pump would bounce between 4-4.6v on the same WDI Race tune this is with 205/30 injectors, I’ve got WDI high flow stand pipes in it as well. I have pressurized the system through the ipr port @110psi with no leaks. Anyone else running bigger injectors with the thumper 1 if so what icp v are you running?

I ran a thumper 1 with 205/75s on an otherwise healthy truck and it wouldn’t maintain icp better than the stock pump. I wasn’t impressed.
