If you live near anyone with the F/T interface I'm sure they'd be happy to do yours for a few even mail it to them.
Flashtune. They'll keep reflashing it for free so I see no need for the interface as my PCV and Autotune will handle fuel. $200 buys a lot of postage

I called them today just waiting to hear back.

Good to see you quantified what we all felt with the graves stacks. 10,500 swithover ahhh. I had mine flashed to 10,200. Time to relfash. How much of a difference did you see from the to swithing points from 10,200 and 10,500?

I cannot recall the exact numbers on each RPM setting, to many runs and result to keep all data. All of them was very much the same until opening point.

I cannot explain way, but top end power went down 0.7-1.5 HP on other settings than 10.500 RPM.

Intake cam is from Kent Cams in UK (www.kentcams.com), exhaust cam is made by Pete Beale. I don't know what he has done with it. Probably some jumbo mumbo black magic because it is really good!!

you may not see the hp nor feel the difference in 12.8 to 13.2 but i promise on shitty us fuel your 5 valve will! the 5 valve does NOT like to be over 13.0 a/f on a dj250 air fuel ratio.. we have seen detonation in summer on bikes "tuned" to 13.2-13.3 when ridden on say a track day. just saying, keep it safe on the 04-06's for sure....big flame spread in those cc's

on a stock engine 10-11k works fine. you wont notice a 300 rpm difference just be sure to tune the fuel correctly after you have flashed. Base flashed maps rarely are spot on...have it tuned..

Those who have bought the stacks, installed them have just said it made a difference – but never given us some dyno charts.
Tired of waiting for proper answer, from otherwise a good supplier, I got hold of some used stacks.
I installed them and today I dyno'ed before and after.

Below you can see the result.

Some info:
It’s the same engine, same dyno, same temp etc. The only difference is velocity stacks.

The spec for the engine is given to me by Pete Beale from UK, and I have promised not to disclose it. So please don’t ask.
I got tired of tuners destroying my engine, therefore I build the engine myself – every single piece.
Edit: Hired the dyno and fuel tuned it myself

Enjoy J
beautiful curves!! I bet Pete has more than a "few" hours in the head! plus gotta be running the YEC springs as you can't put any cam in them with stock springs... but some GOOD specs out there... especially if you can get the intake >250 duration and >10.4mm lift power is all in the top end of these things from what i have seen/done.. head's a mess stock.
