I’ve been running my lml at 600 on stock turbo/injectors and trans for a year now. Made at least 30 1/4 mile passes and several 12 sec passes.
Also ran my lmm with modded vgt at 3200uS for 2 years stock sticks/cp3. Then switched out to 369sxe 10mil cp3 and stock sticks at 3200us for 6 months before I sold it. Lmm was beat on for a few years at 600 and still held together.
