There is a small amount of oil residue in the lines
My theory, mostly fumes/vapor that pass the catch can and accumulate in the form of oil droplets once they condense in the intake tract and later charge pipes
Or.. Oil from turbo which I will check and update later on
Please check..
Mishi was installed on my car and 2 other friends Supras at the same time
2 had zero oil, one had a tiny bit collected. We then all removed the Mishi.. I then added back later on to further test..
We all three then all added a Forge.. All three collected zero oil
All three...
Very frustrating I tried everything.. I know a couple with the same exact issue too
Problem is also oil accumulation in charge pipes and then clamps slipping and popping off (even with T clamps)
Taking car in on Saturday to examine..
With Stock DP it's barely louder than stock, pops much louder
With Catted DP it wakes up a bit
With Catless DP (now) it sounds best. Video of this set up below
On stock flash with Pure800 you will most likely run into torque limit codes and go into limp mode
Full flash is highly advisable
PCV heater core is the sensor that gets canceled, besides throwing a code it won't do any harm.. Tuner coded mine out
