Paycheck Posted August 12, 2021 Share Posted August 12, 2021 Hi gang, I'm in the process of tuning my 2005 LGT and I'm being told I need to upgrade my map sensor because it's maxing out. My tuner is saying to get a 3bar sensor, but I'm also being told by a vendor that the stock one IS 3 bar. However, my data logs suggest that my sensor maxes out at about 18.4 psi or just over 1bar. I tend to trust my tuner/data more than the vendor, but can anyone tell me for sure what the stock sensor is? Thanks, $$$ Link to comment Share on other sites More sharing options...

Paycheck Posted August 15, 2021 Author Share Posted August 15, 2021 Thanks, Rhino, I actually have already gone ahead and ordered the Cobb 4bar kit for the LGT. I also ported the waste gate which helped a little bit with the boost creep. I figure, if my tuner is telling me I need it, I had better get it done. He's the expert, not me. The only things I know how to do on a car I learned from YouTube or this forum. LOL. $$$ Link to comment Share on other sites More sharing options...
