ive read that it is a good idea to get these if you plan on pushin over 20 psi. my question is if i dont get the reflash ecu, would it actually add any hp or tq with just putting on the 3.0sensors? if this is a dumb question i understand if no one responds. thanks in advance.

 

I run 24 psi daily and I don't have GMS1 sensors... YOu can get them from vendors on this site for pretty cheap. Don't go through GM for them

 

i believe you would still need to tune for a 3 bar map sensor.

 

Would the sensors help maintain a peak power of boost at all after being tuned for? I heard it was possible from somewhere

 

I have a set of the GMS1 sensors that I'm not using, not 100% sure on where they are but they're in my house somewhere.
I've read that Trifecta I think tunes on top of the GMS1 tune but I'm not sure if you need the GM tune or if you can just use the sensors.

 

yea i havent heard of anyone doing this. i know a tune would benefit with the sensors, but was just wondering if there would be any benefit to having the sensors on there. basically will it f up the car if i just put the gms1 sensors on? thanks for the help.

 

You have to have a GMS1 OS to run the sensors. (Or tune for them with TF or HP Tuners.) I have them on my car and paid 50 something for the 2 of them shipped. (The 2.5 bars are more expensive for some odd reason.)

 

great thanks for clearing that up. so how did u get those sensors so cheap? why does gm charge $500 for them?

 

76.00 here The Home of WERKSracing products!

 

or you can pay 599.00 for it here with GM's crappy tune

sweet thanks bro. do u get both the map and tip sensors with bosch? do you need both for getting a custom tune?

 

Get both sensors and add the Pigtails from Werks

Simple install

 

Yes you need both. They come in a 2 pack anyways. Opt for the pig tails. It also comes with good directions.

 

supply and demand , a lot more 2.5's out
