i run Meccamo 25%,around 1.5 gallons so far,pipes i have;reedy 2035,RB 2045,all rb manifolds,AXE 2050,OPS 2010 adjustable square manifold,Alpha 2090 variable tip size,Nova long & short manifolds,any thoughts on those or suggestions will be greatly appreciated,and passed on to the growing army of FUSION X Engine owners down under
thanks for your time,cheers guys,

Welll scott , your clutch and a free drivetrain is very important as well but I have personally been using the 9901ss/41021 combo with the X7 in the truck .
If you are gonna run 25% I would drop the shimming .10mm or leave it and run 30% like they should be ran with ,
The 9853ss pipe is known for the super punchy low end , just let Dave know if you need anything
