guiguilandry is on a distinguished road
replace the plugs... do the outside coil setup like ION and I did.. relatively cheap and efficient... I was missing fire at only 5psi above 6000rpm because the stock internal coils were weak on mine...

next check your fuel pump to make sure it has enough pressure AND flow... what injectors are you running ??

also make sure to test or recalibrate your wideband if you can do it...

check your transmission fluid... and let it shift alone... if tuned properly it will always do better shift than you manually shifting it....

and I still can suspect a bad tune...

p.s.: on my LD9 I run 2 step colder a only 5 psi..
on my L67 I run full race plug 4 step colder at 16 psi
