Harlan Shift Light - Help Me Pick Correct RPM Setting
Mods are in my signature below. Rev limiter is currently set at 6700 rpms due to needing a bigger fuel pump. Once new fuel pump is installed, the rev limiter will go up to 7000 rpms. Right now, I've got the shift light set at 6500 rpms, but is that too high with the rev limiter being set at 6700? If so, what should I change it to?

Me personally I would set it at 6,400 or 6,500 that way by the time you shift it'll be around 6,500 or 6,600.. But im no expert.. Btw where did you buy the shift light from if you don't mind me asking cause I need 1

I bought the Harlan shift light off Frost's website. I'm sure you've heard of him; he's one of the best LSx tuners around. Just google his name and you'll find his website.

I was just thinking maybe lowering it down to 6300 or 6400 RPM's because once the light goes on, it doesn't take long at all to climb another 200 RPM's and hit the rev limiter. I think I'm going to change it to 6400 RPM's tonight. Thanks for the help.

No problem. Make sure you print off the directions on LS1 How To, as they have a write-up on instaling the Harlan Shift Light. It also shows you how to program the dip switch inside the shift light for the correct number of cylinders and your desired RPM. Let me know if you need any help.
