i have a t2 the an s4 tps and there is literlaly no tps sweep. when the throtle is at 25% the tps is reading %100. it is working correctly but i know that the s4 tps's are just not that good. what do u guys recommend for and upgrade tps on a stock throttle body? mabey a s5 or a haltech sensor?

 

The S5 is the easiest swap. You'll need the sensor and the throttle body.

 

On a microtech the s4 tps is all that is needed

 

It honestly doesn't matter in most cases with the Microtech. All the Microtech uses the TPS for is to detect if the throttle is at idle, and to do flood clear. By default accel enrichment is done via MAP.

Unless you have some porting that requires you to switch to alpha-n or TPS based enrichments, then the S4 TPS is fine.

 

S5 LIM, port matched to FD UIM, TB and elbow. Wire up FD TPS, i heard FD's have good TPS systems....But Aaron brings up a good point.
