ok so i have a hypertech do you think i could take it up and more then the stock rev of i think 5750 i have a completely stock bottom end with the mods in my sig. Now if not what would i need to do so that i can such as roller rockers or springs?

 

I turned mine all the way up so that i was shifting at 6000rpms, but i would just sell that hpp3 as they are crap and get a mail order tune, i got mine from www.madz28.com.

 

but is that safe on a stock bottom end?

 

I don't see a cam in your sig, is it stock? If so I wouldn't waste time raising you rev limit as the engine isn't making power up there and shifting that high is just slowing you down.

Get a cam, then raise your rev limit.
