Longer the Better!??

After we built engine for this S13, she was tuned when after run in 2000k.







And made around390kw at wheel........And Today.....came for check up....after almost 20000km.



Just in case, set on dyno and check..................


Fully forged 2.0Liter engine, sleeved, and HKS-F-con V-pro.



We adjusted fuel little bit......However the result...............


Power

Boost


Misfire at 6000rpm....still same spark plugs from run in.......need new one!! almost 20000k use...... but...We didn't have any(*_*)""""" well, leave it to the owner.....hehe!

So longer run in is Better???
