Result of testing three pipes, two throttle bodies and two cam sets. Basic curve and peak numbers didn't change much but was too far to the right for me so we kept making adjustments to pull it left and break 100TQ around 2500rpms. The "dip" early is typical of the Prostreet pipes; not felt under power. Pulls hard, very rideable power, no compression issues; 50mph roll on in 6th gear are not challenging at all. Not something I do often but the little motor will pull it willingly. The "square" peak numbers are the results of the Cyclerama cams; I am believer.
