Ok cutting to the chase here: Just completed this mod list: 1. Thorley headers(strock CAT, no mufflers straight pipe all the way back), 2. PVC valve, 3. spark plugs-(gapped 35), 4. TCI Street Fighter Transmission, 5. TCI Rv/Tow Torque Convertor, 6. New gas tank, 7. rebuilt T-case... List of performacne issues at hand: 1. Lack of take off power (less than before mods list) 2. Wont downshift for "passing gear" use.<font color=red>(Even if I mash it to the FLOOR!!!)</font color=red> 3. Shudders once the Torque convertor locks in at lower speeds 4. Hesitant while accelerating (<font color=red> Jumps back and forth between running good and bad in a split second,</font color=red>) 5. Sounds like fuel pump is making a loud buzzing noise 6. And randomly it sorta stumbles <font color=red>(falls on its face) at stop light while idling and under acceleration)</font color=red> I have adjusted the TV cable, First one Ive done so Correct? I dont know. Could the EGR valve be causing some of this lack of power stuff? I need you all to dig deep here. Thanks in advance. I'll check replies in the morning!
