I just had my friend put in brand new stock turbo's. When I first start up the first tubo hesitates and stutters alittle. without the second ever coming on. Then after about 10 min. of driving the first will pull normal still without the other ever coming on. My friend said the wastegauge is not working.. Does the sound right? Does each turbo have its own wastegauge? Thanks for the help ? ALso the a/c compressor is going out. Where is the best price? Also the power steering is leaking , he said it is the hoses colapasing. Just one thing after another. But the first thing is the second turbo.
