i want to buy everything but the tune basically for the LNF GMS1 kit. does anyone have the part numbers and how many parts/sensors are in the kit. the lady tried telling me the whole kit was $700 and only had 2 sensors but that does'nt sound right

3 bar sensor and the pig tail from a vendor

If you go trifecta tuning though you dont need these sensors.....

 

is that really all it is? just one sensor and a pigtail. i only want it so i can trifecta tune it and use my RPD

 

Performance Autowerks, $86 with the connectors & pigtails.

Get the GMPP tune base file for HP Tuners, and go from there.

2 sensors, (GMPP base tune & HPT) or Trifecta.

As was posted Vince at TF can tune without the sensors if you want. I like the better boost control with the 3 bar MAPs.

Waiting on the TF/HPTunable tune to arrive now.

 

thanks everyone who pm'd me and responded

 

its 2 sensors..well you need 2.

 

I take it one senor goes into the top of the intake manifold and the other goes into the cold side charge pipe?

 

From the factory, you have a 3-wire MAP sensor in the manifold, and a 4-wire TMAP in the coldside pipe. The GMS1 sensor are both 4-wire TMAP sensors.

 

ok ok...

so I found this site:

GM Performance Parts -- LNF Turbo Upgrade Kit - GM Techlink

now, with what you said having a 4-wire TMAP in the charge pipe...would I only really need to buy 2 of these 3 bar MAPs and 1 wiring harness? You know what I mean?

 

I have rpd and a trifecta tune no problems at all

 

You have to do both pigtails. The factory TMAP is 4-wire, but with a different connector.............of course.

 

*******...damn connectors are damn near $70...when the sensors are only $15

 

They gotta jam it in somehow.

 

There is NO benefit to having these sensors with a trifecta tune. Your RPD will still work fine without them.

 

I don't have an RPD

Yea I agree...

I'm just trying to get some info on these things so if I have to pull the trigger and get some, I know whats up. As of right now I'm just going to get another 2.5bar one if I can find one or I'll just order it from GMpartsdirect or something. If it craps out, then I'll upgrade to a 3bar

 

Yeah, I wouldn't do it unless it was a last resort. Be sure to install them yourself so you don't have some newb idiot doing it.

 

True, everything will still work fine. Ive had the GMS1/22psi Trifecta tune for a while with no issues. But in MY particular case now on a 24psi tune, a combination of my driving habits and NLS while on tune have cause me to go through 4 manifold MAP sensors. This only started hapening after I upped the boost to 24. They lasted about a month and then would pop. Some ppl havent had any issues boosting higher than than and not popping MAPs. I have. That being said, I purchased the WERKS kit with pigtails and Im going to install this weekend. Others that have done the same agree that it gives you a little more control fine tunning the boost and no more blown sensors.

 

I've been boosting around 25psi for awhile now...and just now have an issue...so yea

 

Hey, for the price, the WERKS kit is a good deal. GM wants like 80 bucks just for the connector! lol I like my 24psi tune and figured why not try the kit out and see what happens. I may need to invest in meth soon too

 

I just ordered mine this noting let me know how the install is

 

This is true...

 

is it hard at all to do the swap?

 

I would assume if you can strip wires and stuff...prolly not

 

Yeah Ill let you know how it goes. Ive gotten tips from other members that did it and the general consensus was to take your time and double check your wiring. That and follow the GMS1 install instructions to the tee. Right down to using red loctite on the bolts since your down to using one from two bolts. Otherwise its straightforward if your good with wiring.
