This thread should be changed from Average TQP Tune to DISTASTROUS Torque Performance Tune.
This car was tuned in 2014 as per below at approx 91,000km.
The owner was a chef and basically took the car in regularly for servicing and paid whatever bill Torque wrote up for him.
He worked, lived and parked in CBD and drove the car on mostly on long trips to visit family.
At the time it had a downpipe from Subtech+K&N intake system. Everything else was stock
I purchased the car in May this year. 105,000km
Did the necessary general servicing, made sure all fluids were changed and fresh and to the right levels.
Took it to a controlled testing day at Pukekohe. At this point, I had only driven the car for less than 200km all up.
Did 3-4 warm up laps and on the 5th lap, engine seized abruptly. Turns out the bottom end bearing was gone and the pistons were melted, stuck together.
Damage to cam gears as well.
My mechanic got a brand new OEM shortblock kit from Winger, fitted to originally head after a lot of cleaning and machining with new cam gears and cambelt done, along with clutch. Took my time and wore in the engine and clutch over next 1000+ km, using 2 changes of run in oil before switching to full synth.
We fitted a boost gauge and notice boost spikes all over the show.
Fitted a new stainless 3” midpipe and a DW65 then went for the tune last night- aiming for max reliability and useable torque instead of chasing any power figures.
The tuner found that the maps by Torque Performance were badly written. There were things that shouldn’t have been fiddled with.
The boost cut was non-existent at 3bar… and the car was knocking bad.
The red shows base run (on Torque Performance Tune) and the other line shows the result of hours of unf***king TQP’s mess.
The 2014 tune was completely messed up, as it took the tuner 2 hours to undo all the changes that Torque Performance had made, prior to carrying out the ACTUAL tune which yielded another 103nm at 3000rpm as per dyno sheets.
The 2014 tune that was in the ECU was extremely unsafe to the point that the 2016 tuner was unable to keep his foot pinned down for a dyno run; due to excessive knock and the 'self learning' capabilities of the stock Subaru ECU.
There was 22 degrees of timing in peak torque + the amount of timing added via Subaru's knock correction table.
So the car was running anywhere between 22deg-30deg in boost.
WAIT HOLD ON. MY CAR ISN'T ON E85! It’s on BP98!!!!!
New tune has had more than 40-50% timing removed
We suspect that the previously tune was highly causative or contributory towards the catastrophic failure of the original motor at only 105000km, despite a full NZ service history with Torque Performance over a 2-3 year period of which I retained a stack of receipts from the previous owner.
I am collating information and relevant documents and will be confronting TQP at some stage in the near future for an explanation.
