Can someone please tell me why this tune "bounces" at 1100 rpm? By bounce i mean it feels like a tire is out of balance going down the road.
This tune is a 30% increase to injection duration, fuel pressure, and boost.
Also a 25% increase to timing.
This tune also only allows one pre-injection.
I get awesome fuel mileage with this tune, but it does not drive particularly well in the lower gears and rpm, like it is weak, or the turbo isnt spooled up. but i do not get any smoke.
Can someone please give me some pointers????
Thank you
