TBI Spacers
 

Have any of you tried or is currently run a TBI with a spacer such as Poweraid, Jet Power-Flow, Helix Power Tower? I’d like to know what’s you opinion of this part. Does it low fuel consumption and really increase torque? I using a Helix Power Tower and I can definitely feel a change in acceleration. However, I’m still on the fence about the fuel efficiency. If you’re using one, has it done any wonders for you? Forgive me if this subject has been covered already.

Feel lucky if you feel anything. These have been covered over and over again on the Toyota sites I go to. They have been shown on Dyno tests to lose HP on Toyotas. Most feel they are a complete waste of money.

I use a Helix as well on a Vortec. While I can't say it made a noticable difference, It did run a little quicker as shown on my G-tech. it did help mileage too. I found it's an integral part of a buildup when used with other parts such as a cold air intake, headers and exhaust
