Any small tips to help ET?

I don't know….

If I track a street car I always run it exactly as it is on the street. Normal air pressure, crap in the trunk, all interior in…… I figure…. It is what it is so I will run it like it is.

I bet a converter change alone would get you in the 13s if yours is stock as mentioned. If you have wheel spin get a set of steel wheels and slap some slicks or drag radials on them (another option).

What are your MPH and 60' times? (MPH and 60' times tell us more than an ET)
