RE: Fuel? Glow plugs?
James... You can run the OS 8 plug and other than it a medium instead of a hot plug it will work fine.. You just can't use the EZ start with it... Byrons fuel is fine... I run traxxas fuel in my Traxxas engines because it works fine.. but you can run whatever you want as long as the oil content is around 16-18%... you will be a little down on power with 15% but not much...
As for the bog off the line and when shifting.. Give the motor a few more tanks to really open up and then tune again... sounds like you are a little off.. can't tell which way by your description... If you stiffen up the rear of the truck too much, you will have bigger handling issues.. the T-maxx is known for its super soft suspension.. it will squat when taking off and lean in turns... As for standing straight up when taking off... It will wheelie with a 2.5 and go pretty fast... If you want crazy wheelies.. get a 3.3 or and OS engine...
