AKSSS Posted November 17, 2013 Report Share Posted November 17, 2013 I haven't seen a stock replacement 3bar sensor. You have to go aftermarket and run a vacuum line to the sensor. Doesn't mean they don't make one. But I haven't seen one. Quote Link to comment Share on other sites More sharing options...
Link2603 Posted November 17, 2013 Report Share Posted November 17, 2013 I thought David steck made them. I bought a 2.5 bar map from him that plugged right in. He custom makes them. Just look up DSX Tuning. Quote Link to comment Share on other sites More sharing options...

Link2603 Posted November 18, 2013 Report Share Posted November 18, 2013 I knew for sure he made a 2.5 but wasn't 100% on the 3 bar. He's a great guy to deal with Quote Link to comment Share on other sites More sharing options...
Bigtoyz97 Posted December 18, 2013 Report Share Posted December 18, 2013 I don't know if it matters anymore or not. But I used one from the old firebirds that were turbo'ed that is 3 bar on my 97 LT1. Quote Link to comment Share on other sites More sharing options...
2003_SuperSport Posted December 19, 2013 Report Share Posted December 19, 2013 I don't really see the need for a 3 bar sensor unless you are making more than 20psi of boost... As a 3bar sensor will have less resolution than a 2bar and most low to medium boosted engines don't run more than 15psi anyways... A 2bar sensor is good to around 200KPA above atmospheric pressure which is around 100... So unless you are maxing out the 2bar above 200KPA there is no need... My kpa only gets up to about 175 at 9.5-10psi of boost and is plenty readable for accurate tuning... Quote Link to comment Share on other sites More sharing options...
12secss e.mack Posted December 19, 2013 Author Report Share Posted December 19, 2013 I needed a 3 bar map sensor, I do run 25psi of boost on a over built LS motor .over driven crank pulley and over driven TVS 2300 Quote Link to comment Share on other sites More sharing options...
