Ed, just do the airbox mod already.
I purchased the moded air box & had several org.members donate there maps for comparison.It isnt a matter of just doing it.it was just my attempt at alittle research & wanting to help other busa owners with any questions on this mod.this is a busa forum right?maybe I would get a warmer recieption if I did a poll on the best color for a busa or some current event that is not busa related.
Switched air boxes yesterday & tried several passes on the ASS dyno.
first,I chose the map I felt would be best by feel,charts,altitude.
second,I ran the stock filter,k/n & bmc.(you can feel & hear a difference with the bmc race filter.)so obviously I chose the bmc race.
To make a very very looong story short.
The air box mod actually hurts your performance when it has a stock exhaust.when the exhaust is replaced(in this case a rs3 full system)you will diffently benefit from the mod ONLY WITH THE PROPER MAP.The sound from the air box is impressive,the rpm's climb way faster & the ASS dyno went off the charts.LOL.
While checking to see which filter,air box(stock & small mod)ran best I ran across another issue the T.R.E.
I found that a map supplied by a Org.member that does not run a tre. & has properly tuned without one.I have diffently seen for myself that with a proper map you will not need a tre.I turned off my GI pro & it ran smooth like it did when i first installed it.I was a believer in this tre.but now it will diffently stay off.

We rent irwindale race way for a day for our customers to run there cars we built.Im either going to buy all full race leather & try this again at pomona or wait till november to go back to irwindale.there isnt a local dyno around here that will do a busa so the next thing is a good old fasion flogging at the track.When I get around to it (if life permits)I will go to the track & post my #'s with the different maps,filters,air boxes,tre,v stacks & maybe sprockets.
