so you've gained a little power at the top end, between 7k and 7.5

but seriously, WTF is going on with that torque?

170lb/ft is a nice peak at 5k, but thats the only positive since it drops right off at 6k plus. im with rob, get it mapped elsewhere if the fueling and timing is spot on...

adam 20lb/ft drop in 500rpm is pretty significant... will affect performance noticably i would imagine, particularly sprints

yeah Rob, previous map with the new manifold might be smoother, original torque line is actually really good, is 5lb/ft down on peak, but keeps the torque at 165lb/ft between 3500 and 6500rpm, and thats what you want for midrange punch. the remap might peak at 170lb/ft but by 6500rpm its already 20lb/ft down on the previous setup

the first 2 graphs are typical TB graphs, power climbing all the way to the limiter, torque being instant with open throttle

the second set look like mine with a buggered plug
