right now my ecu is tuned to 6800 fuel resume and 7000 fuel cut off. which is stock redline.
My friend said i can set the ecu at 7500 fuel cut off.7400 resume and rev it all the way up there, does anyone know if I would be safe doing that, while boosting. b/c i may do that if its safe for daily driven.
All done by using Uberdata.

LS's dont have a very good rod to stroke ratio so they dont take to higher revs well, you can rev it that high but it wouldnt last long

I dont know that I would go over 6800. how much more power are you gonna get out of a next to redline rev? its only 400 rpms...

So the question is not will it blow up at 7500rpm, but will it make any power past 7k rpm?
