Most cases Ive read about are that guys do it a few times, think they have a unicorn, then the converter explodes. Goodluck

Side note - please get a decent, properly spec'd converter before you ruin everything with nitrous. You would net low 11s with heads, converter, and tuning and the car would be much more reliable.
I'm basically just trying to go as fast as I can with the current setup that is far from efficient. I just updated my hptuners config to log TCC slip and duty cycle so I can watch it on my next few passes. This winter the whole powertrain will get a good look over. If I decide to keep the car as a 5.7 NA setup for next season then I will de-cam it to get the powerband in a more reasonable range. I have to look into what is considered acceptable slip for a 4l60 converter...obviously 900 rpm seems to be unacceptable. On the oem stuff I work with I see 400-500 rpm slip at most.
