As you have prob read, I recently dyno tuned my 96 TA WS6 car after heads,cam, and shorties w/ very dissapointing numbers of 297/321. Today, i tried to start my car for the first time in 4 days. Is about 45 degrees outside, car would not turn over for several minutes. Left car came back 2 hours later, car started on 5th try, ran fine w/ no surging or weird idle, yet the SES light is still on, even after I replaced the dead O2 sensor. Still doesnt feel like the power it had after the dyno tune. Any ideas?????????Please help. Opti? Need new ignition? Has new wires/plugs.
