1mm less lift = about 20-25% less fueling.



You found your fuel problem lol Bob G

Lol yep.

Just waiting to hear back from apr

Their coating on the piston looks like it was flaking away and exposed the bare metal which lead to excessive wear

Apr is trying to give me the run around...
They are trying to blame a punched through cam follower, even though I sent them this pic

Ordered a present

Really. That's garbage. They can't just man up and say sorry we can't cover a 6 year old pump?

Just did the IE Internals myself. It's a great piece! Very satisfied with it. Can't believe the customer service of APR, after all you've gone through with them.

Just like APR not taking responsibility.

I look at APR like the wizard in wizard of oz lol , nothing matches what they say espec performance lol

The scene where they met the wizard

"Don't look at the man behind the curtain" hahaha

FYI I have maybe one of the first 100 built pumps b4 they even had there pump test rig finished as my car was the first customer stage 3 development car just after the SEMA car was done and my pump dosnt look anything like that .

My guess is APR cheap out an coating type, spec on hardness or/ and coating supplies to cut cost later on.

FSI BT guys need to check there pump and cam lift especially one that has alot of miles on them as things wear it will definitely kill pump pressure. Don't forget the prv valve it's mechanical and with alot of SW requesting very high pressures those things open and after while won't be true to there rating Good luck. Bob G

Lol yeah I agree.

The pump is 6 years old but has only 65-70k miles on it.

I wonder how long it's been like that though. It wasn't really noticed until I started to up the boost and log the low/high pressure.

All hpfp components cleaned and dust free. Awaiting IEs internals

Here's a before pic of how dirty some of the parts were

All clean

That bish is going to rip with proper fueling!!

 

[FMX_DBC]

Sweet! Cant wait to see what it can do!

Did 27psi logs today

Will be turning it back down to 25 along with a new file and this round of tuning will be done

Those two blips at the beginning of the video right @ 4500 and then a little before 5500 rpm is that slippage or something else? I get that occasionally depending on how I modulate the throttle.
