Just got back from the shop, I'm uploading dyno information right now. The issues was with the M370 intake manifold. I'm not sure if it was installed incorrectly or something is wrong with it. I did two pulls as you can see from the graph, the powerloss was really bad. We swapped out the manifold and put the stock back one and instantly made nearly 100whp more. Doing only two pulls and no ecu learning, I gained 16whp over my previous setup.
The first dyno is a comparison between my best run and the M370 manifold run. The second dyno sheet is a comparison with the stock manifold back on with my baseline dyno. Again this is no tuning and SES on.
