ok so i finally got my engine running semi decent. i got it timed like aaron told me. now my biggest problem is my tps. i was having problems with it before when i was street ported an never really got it set right. i know its 1ohm for stock. i was thinking that it should double it as my idle is about 1800 to 2100. i tryed 2ohms an it helped a little but what would you guys suggest. also what timing would i use i would like to have some options

 

factory s4 ECU? that's not going to help driveability. Set it to .7-1.0 volts with the throttle closed (fast idle disengaged) just like stock. The ECU's logic is based around that voltage range
