Trans-DaptPerformance Trans-Dapt 2533 Swirltorque Tbi Spacer Gm

As advertised, made in USA, build quality is awesome. Did notice quite a difference in acceleration, idle, and low end torque as advertised. The hardware as gaskets where also top notch quality. Great threading, chrome alloy finish, gaskets have metal plating in them like top brand fel-pro's. didn't need a fuel extension fittings being as how I already have a fuel pressure T fitting installed, without that you may need some, however the return line seemed long enough. Also you'll have to depressed the metal insert on your TV cable(if you don't have a electronic controlled tranny) and re-adjust your transmission cable length(700r4 you'll need to adjust it where it's slack but tight at closed throttle). I also have to loosen the back of my throttle bracket and put in nut as a spacer on the front mount bolt, along with with a longer bolt to accommodate the spacer. Be prepared to either space or angle your throttle cable bracket appropriately to prevent line crinks.

I must admit I installed this spacer at the same time as injector spacer and 18psi regulator spring as well as opening ports etc so can't measure performance of spacer alone but all up I'm very happy

easy hook up! can tell a little difference in the power! I would recommend this product!

Throttle response feels a little better. Colder air going in. The spacer will condensate from the temp difference.

The one I received has some bad casting marks. Expected it to be somewhat smooth. Guess you get what you pay for.

I wanted to try adding one of these to my truck, but didnt want to spend a lot on something that really didnt perform as advertised. This was easy to install, and came with all gaskets and hardware.

Woke up my 91 c1500 like wooow!!!! Wasn't expecting!!!!!!

Instant throttle response and torque gains. The downside? If running a 700r4 you'll need to modify your TB cable's bracket so it is not at an angle with the throttle body, or you'll mess up all the shift points and ruin your transmission. I had to uninstall this spacer immediately after the test drive.
