I just finished installing a Sirio .18 in my T-Maxx. It's already broken in, fired up w/ one pull, tuned it up...good temps, a little slow on throttle response still but it seems to run pretty good. The only thing is that my 2.5R would smoke this thing!! Way more low end, wheelied on any surface...the Sirio...nada... no wheelies!!! pulls hard after a softer start (slipper is almost locked) but doesn't seem to have alot of bottom end. The 2.5R still seemed faster. Maybe I've overlooked something or it needs a better tune...but if this is all it's got...I'm not impressed. :confused:
Keep working with the tune. Once you get closer to the Gallon mark through the Sirio, it will wake up even more. You will not be let down...

heh I don't know, i've heard alot of people complaining about the sirio not having much more power, if any, then the 2.5.
well i can tell ya and tex that the sirio has a lot more power then the 2.5. We both ran a total of like 3 sirio's back in the maxx day. It was a huge improvement over the 2.5. Actually towshen has my last sirio that i sold him and he noticed on the first tank about how much more power it has. Give it about a half gallon before it will start to wake up. Around a gallon its just gonna all the sudden giving you power outa know were.
I'm actually not sure how much fuel has been put through it. I got it used, opened it up and it was so clean it looked like it was never run. I thought the guy told me it had under a gallon through it.
What % fuel are you using, and what did the other guys here use to get those results?
I'm using 20%...Tex and I worked on it through a full tank earlier today, got it to respond in mid range, but when it finally responded w/ some botom end it was 330+ and would not make any power under 300. I'm going to work a couple more tanks through it but if it doesn't start to respond it's gone!
I say work with it some more. I used a hot plug (MC59) and 30% Platnium. If under a gallon is on it, it needs more gas through it to start waking up.
