Save up your money and get an Alkycontrol kit. It's specifically designed for the TB, everything is included, it's high quality and most importantly he will stand behind his product with technical support. Remember, you are taking gas away and adding methenol. If there is a failure in the kit, you will run lean. It will take only a few seconds to do expensive damage. If your dyi kit is not top quality and it fails, you'll be out any money you think your savings by making your own kit. We have no e85 around here and everyone runs Julios kit. These people include racers that participate in TAI that are certainly knowledgeable enough to make their own kit but instead use Julios. Why? Because it's reliable and if they need parts he's just a call away. Another thing, TT alky chips are burned to Alkycontrol specs. If you make your own kit you will need to a lot more tuning.
