If so, I need to make a few things as clear as possible. I've already stated these things in my own thread(s) on my results. In fact, I've even embedded these clarifications right in the first dyno video I made. And it also appears that these clarifications were discussed right in the GTM thread. But here they are again:

• I never did a baseline dyno when my car was bone stock, so it's impossible to say definitively that I gained xyz whp over stock with whatever mods.
• The 254whp figure comes from another 6MT 370Z /Sport, dyno'd right before my car, on the same dyno. But it is not the same car, so at best, this figure can only serve as a rough approximation baseline.
• I installed the Stillen CBE and Berk HFCs at the same time, so I do not have separate numbers for these two components.
• If you use the 254whp number as an approximate baseline, then my 291whp figure appears to support the dyno results that Stillen claims for their CBE (+18), as well as the results that DDM got for the Berk HFCs (+19).

When you look at the totality of circumstances, I think the +37whp 'gain' my car supposedly made must be taken with a HUGE grain of salt. We certainly cannot claim that the Stillen CBE alone made +37whp. There's just no way.

I hope this clears up any confusion.
