What is causing my TQ to roll over around 4500rpm versus staying flat like most S/C'd vehicles?
I recently had my car re-tuned after changing over to a return system. I have not had this engine/blower setup on the dyno prior for comparison. The car runs wonderfully, infact if i hadn't decided on putting it on the dyno to do a pre/post E85 pull on the dyno i would have never thought there was an issue.
I think these are all the pertinent details needed to make a assessment but if not ask away. I have built this car myself top to bottom.
Attached below is a copy of the dyno pulls and the data log for these pulls.
