well they said they got those results from an 01 Z06 so they had a beter starting point then a ls1 (hp wise), figure an Z06 with long tubes, exhaust, full good bolt ons, aggressive tune... that seems to be possible

It says they have a 400rwhp LS1 x-package. Don't know how they can do this, because I've never heard of a 400rwhp LS1 without heads/cam. What kind of magic dust are they using?

If its too good to be true it usually is, but every now and then sometimes things are too good to be true. why do they only do it inhouse, that would get me thinking twice.

This came up a while ago, and one of those guys came on here and posted. It seemed like total BS to me at the time, and still does. As far as I know, no one has made 400 rwhp with stock internals on a LS1. On a LS6, I think it could be done. I wouldn't buy anything from those tards.

OK "Speed Engineering" (LS1TECH Sponsor), here's your chance. You can tell us what you plan on doing to the engine (like other specialty shops do) and gain credibility with this group, or you can ignore this thread and confirm in everyone's mind that it is BS.
Your choice!
