Did ya feel as if it was worth the $$ ?

i did it for cheap. i know people in the business. i have not tested it yet it has been sitting around for a while. i am going to test it soon. i was thinking about selling it because i want a 96 throttle body manifold

Id like to see some dyno results with the larger TB. I know RSM charges a ton for theirs and I personally don't see it making a huge difference with the rest of the plenum setup. Thats opinion, not fact so I would love to see some real results on doing this.

[d.o.h.c]

well it in and the car is much slower i punched it at a dead stop and it shifts gears at 4,000 have not tried at 30mph though. manybe because the tps sensor is not hooked up. well it sure is louder.

[SappySE107]

Yeha, the TPS sensor has to be hooked up.

[d.o.h.c]

yeah becuase the spedo does not even work . do you think that affects anything

[SappySE107]

No, the TPS is used for shift points. Dunno what the deal is with the speedo though, nothing intake related.

[d.o.h.c]

well i took a look at theshaft and it looks to be off. so at closed throttle i am getting .000 voltes. were i should be getting .50. so i have to bend the shaft back and make it fit that way. it says that the tps has a lot to do with the fuel to so that is why i think my car is so slow right now

[d.o.h.c]

well i bought a new tps sen sensor and i still get nothing. but when i push on the pedal and get the voltage to.50 the ses light goes off. so i look at the shafts of the new throttle body and my stocker and there the same but the tps sensor does not read the right voltage. and my shift point are crazy like shifting at 3,000 floored so i need some seriously help

[d.o.h.c]

and my spedo does not work still think it could be the tps because it stoped working after i switched the throttle bodies
