inconsistent boost

icey756 · 10-07-2011, 05:42 AM

I have been noticing that my boost is different according to what gear im in. 1st is about 4 or 5 2nd is 5 to 6 third is 6 and 4th is 7. I have a manual boost controller under the hood. I can really think of anything that would be the problem i guess. I have an aftermarket boost gauge hooked up and i also have the stock one hooked up. Im thinking either a vacuum leak somewhere or it could be where i have the new one hooked up. Idk. I'm open for suggestions and also a picture of how u have ur aftermarket boost gauge hooked up would be superb.
