Ok boys, tunes and high flowing mufflers are great but don’t overlook your air to air cooler, they are a restriction as well as the muffler on 270 and up tunes so order your precision air cooler as soon as possible before there gone! Wink, wink.

Td multi map, the electronics will bring boost down to where it needs to be but you will see that spike your after.

this is how I achieve more boost by adding an external spring to the waste gate arm, unconventional but does work

The 137 is a blast off trail with a Hurricane 1”75 ,remove the coupling block and add anti stab wheels to front of rails. 17 xtx anti stab will work. It is a hand full set up this way, acts like an old two stroke 500 dirt bike. Leave snow flap on, you’ll need it to keep sled from coming over...
