definitely!
i did an 11.1 with 320awkw (if i changed into 4th across the finish line & not hit the limiter in 3rd, it would have been a 10)
with 390awkw it is well truly a mid 10
i cant see why such a reputable tuner would tell such a lie - they have tuned 1000's of gtr's & that is not an exaggeration...anyway, end of the day it dont matter
yogibear - call crd & ask for jim (owner) he has a great story to tell about his nitto oil pump & hence why i also use nitto...all i will say is that their oil pump can chew cast iron block bits & that wont even stop the damn thing
how is 'boo-boo' these days? man i miss those old classic cartoons
