I am ordering your LNF 1.0 PCM. When I order it I'm also ordering these springs. Can my pcm be pre tuned to bump up the rev limit?

If you leave a note, we could raise the rev limiter for them, however without larger cams and a turbo, you will not need to rev the car any higher. The valve springs are still a great upgrade though, because the stock springs can valve float on basic setups.

Will these springs handle the GM performance cam set? Part number 88958648 with the following specs
Duration @ 0.050" lift is 247° on the intake and 249° on the exhaust
Maximum lift is 0.499" for the intake and 0.499" on the exhaust
Lobe centerline is 116°

No, these springs bind at .500 so they would not work as you need some room
