I have 405whp DD and 344 whp depending on boost maps. I plan on doing a shortblock build with meth injection just for added safety. my daily driver map will be about 480 whp, a 93 octane/meth map of mid 500's and maybe a race gas map for the track of high 500- low 600 whp. Then I will be happy. Anything in the 500 range on the street is getting to be overkill because you can't get traction unless running from a roll. Hope to get this within the next 6-8 months.
