car is bucking at high rpms

[splitsecond03]

i have a 95 gsx eclipse with turbo xs boost controler. i was playin around wit it by adjusting the boost. after i did this at high rpm's the car wanted to buck. how do i adjust it to the factory boost level. i also think it could be the spark plug wires because is no spark plug wire cover on top of the head. looks like arching on hood. please help

Loosen the knob on the controller so the spring is not as tight. The more you loosen, the less boost you get, until you reach stock and you will not go any lower.

What kind of wires are you running?

Running a cover with not keep them from arching....

I would get some NGK wires or some Magnicores (if you have the money, definately the magnicore wires).

It is most likely arching from a break in your spark plug wires, check them.
