Best magnum MPG?
Actually, the biggest problems with a thermoturd is that the base plates warp and suck un metered air past throttle plates. This is my"opinion" after building carbs since 1984, but what would I know about building or tuning carbs, I have probably only built as many carbs as you have owned pairs of socks. You can put a thermoturd on your birthday cake if you want, its doesnt make it any less of a POS than it is. I would not put a square wheel on my wheelbarrow just because guy down the street did, they are round for a reason. like comparing a musket to an ar-15....yawn. BTW FITech is well under $1000 so no excuses for carb made by Mattel.
Back to OT, if you want great MPG out of your magnum, dump the monkey with a bucket of gas dispenser and join the rest of us in the 21st century with multi port FI, otherwise suffer the fate of mi teens MPG.
