Surging/missing Problem Since New Injectors

[Psymon]

I recently fitted GTR injectors to my RB20. Since then i have been having a bit of a missing or surging problem. Driving around at 1/4 or half throttle it drives fine. But when i give it everything it seems to jerk and miss for a second or two... then it comes on nice and hard all the way to redline.

I also get the problem that when i shift gears quickly say from 1st to 2nd or from 2nd to 3rd it will jerk and cut in and out. I have to ease the throttle on so it wont do this. I have to shift so slowly that it takes all the fun out of it!

Anyone have any ideas what could be happening here?

GTR injectors allow a fair bit more fuel, it could be overfueling because of the extra flow, this would make it run very rich and do what your discribing.

It's had a re-map done to suit the gtr injectors.

Get it back on the dyno to see whats going on.
