Yeah, i put those babies in Johnny.
I originally went to 82.5 and whatever on the latrency, as Dale says, i tried a few values on latency but found no noticable difference...and i don't think anyone still has found a decent definition of what this value is used for.
In fact (as i've never replaced em before, 1st go) when i turned the key i was wishing/hoping/crossing fingers that i had it all right, and it was as if nothing had changed at all....super stoked! Drove like normal, no change in fuel consumption, and i drove it like that for 1-2 months (excluding WOT's) until the full tune was done
The 77% is only usable as it's had a full tune.
The tuner at the time said he would find his own setting for that and re-tune the car to suit.
You should be able to (theoretically) have any number there if getting a 'from scratch' tune.
