The thread "programming for dummies" started by OZ was very interesting. I just purchased hpt but have not received it yet. So I'm REALLY new at this. Was that thread specific to LS1/LS6 cars or was it a general guide? If so, is there a topic similar to that pertaining to L67 cars? Being so green at this, I'd like a starting place for tuning. Thanks for any info and I'll post a similar topic in the V6 area.
