I finally made it back to the 1/4 mile drag strip with the cat deletes. My MPH improved to 116.64mph. The temp was in the low 60's. I can't find my old time slips. If memory serves me correctly my previous best was 115 MPH. I have no tune other than Track Key. Currently I have no CEL. I made no other motor mods since my last time at the track other than removing the Cats. (I did replace my drive shaft because the factory one broke.) I don't think the DS will give me MPH though. It might give me ET.
According to a HP calculator, the motor is making close to 490 hp at the fly wheel. These motors seem to just need to breathe.
