Hey guys I'm planning to get protune this spring, the question is which way to go? Currently I use cobb e30 maps and I want more power, just don't know should I get e40 protune with stock lpfp? or buy lpfp (mess with all that headache during installation) and protune e60 to get max power?

Is it a big difference in power between stock lpfp e40 protune and upgraded one with e 50-e60-e70???

Need log to see if you require it.

Yes you can squeeze more boost and advance out of E60 than E40, E60 is pretty optimal for tuning and the benefits diminish after that.

Doubt you can support E60 on stock low pressure, maybe if the pump is new and healthy. But not over the long-term. I’d log and prepare to upgrade, it’s really not that bad an installation.

I would say pull the trigger on a pump, you will only benefit from it, it will take stress off of your stock lpfp and you will be smiling from ear to ear with the power.

D you still running the FFTEC pump? Mine just went in a few days ago..no issues so far outside of it providing way too much flow WOT, like 90 some PSI lol. Need to reset the adaptations…but trims look perfect and I love how the car starts *instantly* with both pumps priming.

Pretty much required to start mixing more E85 to take the power to the next level after FBO.

Even if you did squeak by without needing one you'll be running that fuel pump at the ragged edge.

Pretty cheap upgrade also and tank can be reached without dropping tank.

I have PTF E50 without upgraded lpfp for about a year now pump is still running good but I will eventually throw in a inline walbro soon dont want my pump taking a dump on me...another thing i notice a big power difference between e30 ots map vs my e50 map

Yes I am, working flawlessly since install. I think I am due for the new injectors, I'm still running the old part number, if the car starts up and instantly revs to 2k then drops down to normal warm up rpm, could that be a sign of leaky injectors or is that normal? My throttle pedal is also pretty mushy lately, trying to check for possible boost/vacuum leaks.

Glad to hear you're all set up with the pump.

Good to hear it’s working well for you man.

IDK about the revs jumping on cold starts, when I start the car after work tonight I’ll note roughly what revs it climbs to on start. I want to say it’s more like 1.5K revs but not positive.

Boost leaks always rear their ugly heads. I need to replace all my vac lines, I’m def getting some small leaks and it’s not cool.

No headache installing the inline lpfp

Is there any reason or benefits to running an inline pump if I'm not planning on using ethanol? Will it help anyone who's FBO but not using e or meth?

So it's really beneficial going from e30 to say e60??

I don't think so!!!

Oh yea. Big change in terms of what you can tune for. With the way E60 cools and pulls out heat from combustion, you can get pretty aggressive and still have acceptable EGTs and pressure. It’s good stuff.

Wow it's nice to hear that your pump is still alive esp when using e50.
I was planning to use ptf e40.
And the question is that much of a difference between ptf e40 (stock pump) VS PTF e60 (upgraded pump)???

Nice to hear that kind of things, btw which pump you recommend ??? (easiest installation)

Which pump to choose??? If I want to reach the tank without dropping??

Easiest to install? Walbro inline. Cheap and proven, but easy to mess up the install and reliability is middle of the road. It is not an E85 specific pump, but has been used as such across numerous platforms.

Best in terms of quality and flow? FFTEC E85 Walbro. PITA to install, probably overly complex, certainly overly expensive. But I’m happy with mine.

Only thing I don’t like is how the inlines are just hanging out/floating in the tank, no good spots to mount or otherwise clamp them down. It’s not a big deal but annoying.

See post #82 showing how fellow making an install kit proposes to secure the pump:

SteveAZ is a beast; he’s done really good work on the fueling side. Wish he’d chime in more on this forum.

Thanks!! Will consider doing this, it’s not a big deal but I’m not wild about the pump just floating around.

On a walbro site it says that it's universal pump,and it goes only pump withoit all the necessary stuff to install.

What else I need to buy to instal it properly?
