so where can i find these sensors at an affordable price?

 

CED was selling them, maybe genuine saab.

 

i got them form gmpartsdirect for 494 shipped.

 

wouldnt you have to let the dealer do the install to fully keep the warranty or can you get away with installing the sensors yourself?

 

thats the full kit, the sensors can be bought alone for those who want to tune themselves.

 

well how much are just the sensors?

 

oh I C. I missed that part.

as long as the dealership does the flash your safe..

 

thanks for the info

 

So i was thinking about skipping GMS1 completely but after reading how easy the sensors are I'm interested in maybe at least doing that part.

$207.32 MAP sensors and pigtails +$75.00 flash

around $275 for gms1 sensors with stock tune... then go for Trifecta or HPT= ultimate setup?!

So I'll basically save $200+install by not getting the shitty S1 tune and i can put that money towards a better tune.

My questions is: $275 for new sensors is it really worth it? How much am i actually gaining by doing this? Is my money better spent other mods? Only performance mod i have is catless down pipe.

 

I'll tell you what the benefit to these new sensor are.

The 2.5bar MAP sensor can only read up to 22-24psi roughly.... if you spike above that then your readings go haywire and you can't read boost for the moment. THese sensor can support reading up to a high psi range.

 

im guessing you missed the links two posts up where the sensors themselves are less than 17 bucks each... if you put them in the car you're going to have to retune THEN... cant run them with a stock tune and the GMS1 tune is great for those of us who just bought the cars and still have a warranty that they'd like to retain.

 

OK- so the sensors will only affect my boost gauge being accurate passed 24 psi/not usable after 24psi.

It also says you need 2 sensors and 2 pigtails- totaling $207.32 in ching + whatever the dealership charges to flash.

Right now i have no tunes at all (i'm bone stock) and i'm looking for the best and most cost effective solution to get a great tune- i'm asking if it's worth the money to install the GMS1 sensors first and flash before i get tri-fecta'ed.

 

I have stock sensors and HPT tune (no GM)..more HP than GM1. No problems with max boost around 21ish. Why mess with sensors if you don't need to (ie not above above 21-22lbs boost)? There have been *issues*with installation of these....splicing and positioning..etc. Sure, they have more visibility on boost above 21. If you need that, then go for it. I'm just
doing great the the stock sensors.

 

had my stage 1 for 6 months w/o issues, so I guess you got virgin mechanics who don't know anything about these cars. before I done my GMS1 I made sure I highlighted all the important things on the instructions like which code to enter, wiring, and little things like shave the boss when you flush it down that was it.

 

Terminator went with the sensors and his own HPT tune. The sensors aren't a performance upgrade. They're a reliability upgrade for more accurate and consistent reading of higher pressure levels.

 

in other words they are too conservative. makes it sound like the down learn feature says, "hahaha.... you thought it was the end of me". I personally don't care, my car is fast enough with the catless dp and the cp with GMS1.

 

Excellent approach!

 

I installed mine by myself. Took me maybe 2 hours. Then the next day I drove slowly to the dealer maybe 20 min away without throwing a CEL. Dealer charged me 100 bucks for the flash. It's easy to install.

 

you dont technically need them if you go with the trifecta tune. They really benefit the gm tune and hpt.

 

I was in just that situation. Got HPT tune with NO MODS and stock sensors left alone. Performance is greater than GM tune alone with boost under 22..works great!( See dyno on my image gallery). You don't need GM sensors unless you're going with higher boost levels. I like leaving everything UNTOUCHED. Bolt ons and sensor changes *open the door* for potential problems..those sensors must be installed correctly as well. Any minor *oversights* there will give you grief.

 

but having hpt on TOP of a gm stage 1 tune w/ sensors will be even better. I suggest that as well. the gm stage 1 tune has newer maps for maf etc. You can buy just the sensors for what under 100 easy, install yourself, and have the hpt reflashed with stage 1 + custom tune.

 

I calculated around $275 for just the GMS1 sensors and flashed to stock. It kind of seems like the cost/benefit ratio isn't quite up to my standards for what it will actually give me.

I'll prolly put the money towards K&N intake instead and then custom tune for downpipe and intake and be done with it.

 

Custom tune will work fine..I have one (no bolt ons though). The down pipe isn't exactly cheap and you probably won't get more than +15HP with that. I know because I found someone who dynoed and tuned at the same place I did with the only difference being he had Intake, Charge pipes and DP and I'm stock. I have the Dynoes to prove it. The DP was catless and probably accounted for most (if not all) the gain. I don't think it's worth it (with these mods), since some have had *issues* with their DPs.
