Just curious to why at around 6250rpm the graph gets really jagged, needs more time on the dyno?
the car feels really smooth threw all rpms

 

how old are your spark plug wires ?
have you ever changed a rotor-cap on your dizzy ?

i think is more an electric problem.

 

Smoothing is set to 0 on the chart. There isn't a problem per say.
You likely could benefit from a better flowing exhaust/header/intake/fresh plugs at the correct gap. (possibly I don't know the specs)

Tell them to set the smoothing to a higher amount like 3 or 5 and you will have your pretty chart lol :-)

 

did fresh plugs gap correctly, ngk wires, distributor rebuild before tune
whale *****, 68mm tb, skunk2 im, ebay header, and 2.25" thermal catback; p28 with crome

im losing threw the crappy intake and header but 181/136 is pretty nice from a stock gsr
im going back for when im boosted so ill ask

 

Would have read lower if smoothing was set higher.
