Yes, with an e30 tune in flash form and decent tires/bracing/overall traction it is a 14 flat car on street tires. The more supporting mods the better, the ones in my last 2 posts above, will help you achieve the best possible times the most consistently. I happen to have a custom e50 tune as well and just because of the custom dialing in from datalogs sent helps maximize that (the e50 part is just for easier mixing math) probably pushes it from 14 to 13.8, but I need more practice in launching, I've hit 14.2@102 without the best launches. There are a variety of launch methods and depending on sloppy of wheel hop you have and using a spark based traction control can help. But I won't even get into that as most people are strongly against it and I still have to work on how I'm going to be launching including launch control RPM settings. Fairly low RPM's seem to work best due to how quickly torque is produced and how short geared we are, RPM's around 2750 seems to be ideal, even if doesn't sound as cool at the line.
