2 LPPLP installed

Postby spencerdiesel » Sun Jan 03, 2016 6:59 pm

Two pumps from THD, a 12 and 15 psi. My friend put the 15 on his and his truck pulls STAUNCHLY harder on the top, as well as improved throttle response. Once the hair dryer lights, truck still pulls hard instead of falling on its face like it did with the stock lift pump.

I noticed an awesome increase in throttle response, slightly harder pull on the top (I only have like 30 hp over stock, so that's why the "felt difference" was not as drastic). The biggest difference which I really felt, was the truck keeps pulling after the turbo lights. Same as my friends, before the THD pump the truck would start nosing over right after the charger spooled.

I know few people on here are still running the factory lift pump, but for anyone out there that needs fuel to the IP, get the pump and don't look back.

With some pretty nasty 6x13s from Eric I can only pull mine down to about 10 psi.

Thanks Eric, if not for you we'd all be running TURD POD's

No offense to anyone that still runs them of course

I put the 13 on mine from hungry diesel-
also did new injector tips, IP O-ring s, head studs, new head gasket, oil seals, +60 valve springs, Cro-Mo push rods,
KDP, Fuel turn-up slightly- (20%)
anyway-
when I started the motor again- it seemed like it had twice the power and throttle response.....

Hard to tell how much was pump I guess.....
