2003 SC Where is the Power ?

[Bradley]

Talked to Bob Gardner at TRD today, Bob explained that the 2003 V8 Tundra has an acceleration load limiter built into the vehicle that limits the acceleration from a dead start to help eliminate wheel spin and loss of control on wet or slippery surfaces. he claims the control affects the SuperChargers ability to improve low end accceleration. The 2003 also is listed as an SULEV (Super Ultra Low Emission Vehicle) , he said the Supercharger for 2003 has 2 extra fuel injectors installed due to the lean air to fuel condition.
2000 - 2002 1 extra injector.
Bob said that the best model year for performance would be a 2000 , Bob claims the cams in a 2000 V8 along with the computer Mapping, make for a good performing engine.
Wth the SuperCharger installed on a 2000 an 80 horse power increase could be obtained. He explained they have to work within the engine parameters, they are not able to do a ground up engine that would be designed to take full advantage to SuperCharging, the stock compression ratio is to high to allow the use of more boost, Increaseing the boost to the engine would cause pinging, resulting in a decrease in power.

That seems kind of dumb. That seems to be taking away the reason people would buy it. Do you have any idea how something like that works? Is it computer controled? I would understand if there was a button that you could turn on for less power to get more traction.

the trd blower can produce well over 14 psi with the overdrive pulleys anb the unichip can get rid of the trd computer that is severely retarded at the low end and that is why you cant spin the wheels. with the unichip you get timming advance and and proper use of the nineth injector. also a much better map regardless of the year model.

There are definately two inectors on the 03 supercharger
there was an "update" already (for the o-rings on the injectors)

all i can say is that my s/c 2002 4x4 ran 15.7 at 86 mph and i was not impressed at the track, but pulling away from a lightning on the highway is not too difficult.

I am going to go with a unichip and pulley i think the trd piggyback is holding back the true potential of the s/c ,

Was he pulling a trailer or something? It doesn't figure.

4x4 is alot heavier (500lbs) 15's is the best anyones done with a 4wd without piggybacks, cam and head swaps or turbos. I wonder if Venom makes AFM tranny? Personally the s/c provides enough power and acceleration to handle the highway and tow a double axle tailer. Ill get a sports car to race around in and get to know my local highway patrol better if speed were my agenda.
