91 Octane

ok Map 28

Ok so log 9 is meth spray 4-15psi .. log 10 I turned meth off as mush as possible so started spraying at 10psi , log 11 back to spraying at 4-15...I felt some misses or hesitations after the pulls and during log 9 and 11 but not 10.. This is also with cheveron 91 and royal purple boost octane...My shop put the AEM meth filter in the wrong place after the pump and i noticed its leaking a bit... I have always fought timing since day one of tuning but next week Im having my shop move the filter and then put in the larger spray nozzle as well as look the whole car over..
