Only a pound or two but I feel you would be better off using some form of boost control to be able to level boost out again if required. I have a spoolinboost plenum you can add to the comparisons if your interested. Link to comment Share on other sites More sharing options...

My Plazzy race series is absolutely fantastic with normal everyday driving. As we only have a base map in it ( more road tuning on Sat), I expect that it will only get better. Have you tuned many Jet? The majority that I know with Hypertune's ect. All have big cams and vernier gears. I'm guessing that drivability isn't a concern for those guys. .. 1 hour ago, turbo_will said: Every time I have done a bigger plenum swap on spring pressure I have found the boost has changed with a drop as rpm increase.

I think that the test mule will be running a gtx55 turbo, so we might stretch its legs a little.... Link to comment Share on other sites More sharing options...
