Your timing is way to advanced if thats your base timing.

Turn it down to like 10 or you could cause major engine damage.

Are you sure that your balancer is correct cause I cant believe that you havent blown it up already.

Ive heard the stock balancers can slip a little and give false timing readings.

Can anyone else chime in here??

Is the chip burned for a blower or n.a.? If it is a non-blower chip I would yank it out ASAP. Then you want to verify tdc on the balancer, make sure the timing is set at 8 or 10 btdc with the spout connector pulled out at idle. You may want to get the chip reburned for blower use, might pick up a little power. Do you have a 30# calibrated MAF or is the chip required to run the 30# injectors (mimatched MAF)?

Fuel pressure should be at 38 to 42 psi with the vac line dsiconnected. Reconnect vac line after checking.

yes it is burnt for the s/c and the 75mm maf and injectors are calibrated so today i will change the timing and the fuel pressure to 42 and i'll let everyone no how it goes

I took you posting as saying 22 degrees total with advance. So you would be at 10 degrees at the balancer with 12 degrees advance. Was I reading this correctly. Your timing would then be correct. Your car would not even start or crank at 22 degrees advance.
