Hey im gettin my turbo LS ready to get tuned and the tuner told me to get a 3bar map sensor... I was looking at the map sensor that is sold on ebay for $109.00
Can this map sensor be trusted ? or does anyone have any suggestions... the tuner told me that he tunes with neptune

 

The GM 3 Bar should get the job done...

 

I would recommend purchasing a omnipower/hondata 4 bar plug & play sensor.
No wiring needed, simply bolt it on & tune.

 

I would also recommend the motorola/hondata/omnipower 3bar.

The GM 3 bar just does not have the scale or linearity of the motorola sensors. I've had bad luck with them in terms of driveability, tuneability, and reliability.

 

I have the OMNI power map on my DD, works great, and they send you the offset and scalar so its calibrated perfectly

 

ok thanks im going with the omni power map
