I'm looking into doing some fairly easy and inexpensive mods. I'm planning on full exhaust and I'm considering aluminum roller rockers. I'm wondering if going with stock ratio 1.5 rockers will yield significant gains (they claim up to 15hp)? I'm also curious as to how much 1.6 rockers would upset the SD computer? Obviously if I can use 1.6's without a problem that'd be better, but I also know that the SD computer is kind of sensitive. Thanks for the help.

 

that little bit of change in the lift wont effect your ecm.

I have a set for sale but they're non self aligning
