jiako,
Send $100 and I will spend $200 on two seperate dynos tuning sessions.
One with butterflies, tuned for proper a/f ratio.
One without butterflies, tuned for proper a/f ratio. Then we will have an answer.
The problem with most "pinned" secondary dyno results is that it doesn't adjust for the new found air increase. True mod comparison is done with 12.5/1 a/f ratios. Otherwise the PCM can't adjust for the added air.
IMHO, slapping on any kind of air or fuel modification like an intake, exhaust, et al, without proper a/f tuning is not a good way to compare. TB and MAF sizing dyno grafts are another false comparison. They change the TB without increasing the fuel.
Anyone with 14s or less 1/4 mile times have a/f tuning, or did you not notice. ie DemonSVT, Bnoon, Warmonger, et al.
