R32 Gtst Timing Droping 2 1 Degree

[r32psi]

I recently got an r32 gtst and my timing's retarding to 1 degrees advance. from roughly 5000rpm to 7000rpm it bogs down. after 7000rpm it picks up again... if i turn the boost up which is only on stock boost it coughs and splatters at 5000rpm... ive got the timing set t 30degrees advance and it drives better at that. but timing still retards to 1degrees as soon as i touch the pedal. can anyone help me please????

how are you checking the timing? with a timing light or on the ecu? either way, the timing doesn't stay the same throughout the rev range. that is the point of the ecu. it controls the timing. either way, 30 degrees advance is WAY too much timing (if you have set that with a timing light at idle). it will ping its arse off and destroy your engine pretty quickly. you should have your timing set at about 15 degrees.

as for the bogging down, that is more than likely going to be caused by either faulty coil packs, ignitor or spark plugs. although you may also have a faulty crank angle sensor

timing was set with a timing light. but i had a scaner on it 2.when i hit the gas the timing drops so its not pinging if i set the timing at 15 degrees coughs and splatters
