hey everyone, I have a mcx 270 viper. Sled is running okay but takes a fairly long time to gain rpm and a fairly long time to build boost in my opinion. All boost connections seem to be good. Anyone have any opinions on what this could be? Just had the sled remapped for the new update to fix altimeter problem. Can't get this thing to run great. Should be kicking on the 2 strokes but it's not being very impressive

Air intake through the hood helps alot also too much weight on the clutch arms really bogs them down

But that's with 24-41 gearing on a xtx with 21-41 it took a lot of weight to keep it off the Rev limiter

What's you max ground speed? I got xtx too converted to 162 and its retarded fast in my books. Over 100 mphBut that's with 24-41 gearing on a xtx with 21-41 it took a lot of weight to keep it off the Rev limiter

110 with stock gearing with new gears acording to the gearing chart should be 126mph
