Thanks, I would never boost w/o doing internals. That's why I asked about the correct compression for new pistons prefferably stock bore. And that's why I'm only looking for 250-270whp so my ATTS will NOT be rendered useless. Unfortunately, I'm stuck with the SH. And I still need to know if there is any engine management that will allow ATTS operation as stated above.
Thanks again
