I am currently running a stock fuel pump, 370cc injectors, and a cartech FMU on my 04 eco. I am getting ready to get my car tuned by hpt. I am wanting to go with a Walbro 255 in tank, and a good fpr. I am wondering what kind of setups people have had good results with, so I know what to invest in. thanx chris

you dont need the fmu if you are getting/or have hptuners...

get a afpr... and a wideband...

i ran 15psi and got 13.2 in on my stock fuel pump so its pretty good, im pretty sure i have maxed it out though no way to know for sure until i get to see my fuel pressure under 15psi of boost though

if you're going for more power get the walbro, and upgrade the wiring so there is always juice flowing to it.

Personally, I'm the only person I know and have seen running one, but I'm running a universal AEM regulator.

I think if you do a quick search you'll find a plethora of info on what Adjustable fuel regulators people here prefer.

W/ HPT, you're gonna want to somehow get a 2bar program on there too.

I know I don't need a FMU nemore acer. I was just curious at to what setups you guys are running with HPT and where you got the fuel system stuff from, cause I cant find many in tank pumps at all. Just alot of inline ones. Say if I bought a inline pump would I still have to keep the stock one in the tank. I am having Ryan from PnP tune it with his hpt, he lives like 5 min from me. So we should be able to get something going, I already have a 2 bar map out of a LS1 so im gonna see if my ecotec will take it or not.
