Re: 04's L32 motor
You get a PCM and you'll hit low 13's or at least 13.5.
The thing about the 04 compared to the 97-03 cars is it's like having a Stage 4 ported blower, LS1 TB, no U-bend, and lighter weight rods right from the factory. So it will get better times with less mods with a aftermarket PCM. The alcohol makes difference you can feel.
The biggest killer for the 04's is the PCM it's TQ Management kills your performance.
