I got a T2 and waiting to get my hands in the LT8.. The previous owner said the Stock S4 TPS didnt work very well.. Some suggestion ?

 

I just got a full range GM TPS from a blazer.

 

the stock s4 tps works fine.

 

The standard tps works excellent.
You have to understand that all the tps does is switch from IDLE to LOAD maps.
So as long as it goes over 20% when you hit the accelerator and it goes to zero with no foot on the accelerator then getting a full range tps is going to do jack sqaut.

 

Ahh okey. Im still using the stock tps and wont change it

 

Is it true that a GM TPS can be installed without reconfiguring the Microtech?

 

yes you can use any TPS you like and dont have to get reconfigured

 

what if you want a throttle pump above 50% throttle?

 

depends how you tune and what you use the tps for. IF all you want it for is idle/load switching, then yea you only need the s4 one. But if you tune other things with it, then you want a full range.
