alright heres the deal... i had mine in the dp for a while and it worked but it defanittly was not acuarte...kindda LIKE my spelling... but... it worked for the time being at idle you will read like 200 but when you get on it and drive your car it goes up to like 8 or 9 and maybe 11... i recently juz went with a diffrent turbo... rnr 50 trimto be exact...and tapped the number one cylinder on the manifod and it now idles at 800 all the time and when i get on it its at like 12... hopefully that helps you out... if you ever get a new manifold tap it and put it there... makes a big difference!
