4AGE 20V Tuning
How do i tune my ST 20V for best performance? its sluggish at the low rpm, then gets a burst of energy, and at high rmp it dies back down again. The person i bought my engine from seemd to have screwd around with the AFM, so im thinking that may be a cause. Also i tried shifting my TPS to see if this will help, but theres only one spot i can keep the TPS because if i were to move it, the idle would raise dramatically. Is this normal?
There are three vacuum hoses on the right hand side just ontop of the fuel rail. One is the ISCV, and the other two i dont know, so i blocked them off, where do they go?
and i've set my ignition timing at 10 degrees.
So i've tried my TPS, AFM and ignition timing, and still isnt running 100%, actually not even 75%. any info will be great.
