Definitely no clutch slippage-I know what that feels like. This beast has a few refinements- intake snorkels removed, Stucchi xover, MIVV cans with shortened dB killers and the 02 LeMans map. I ran the Ti map until a couple of months ago. At that time I shortened the killers and uploaded the LM map. Now, this thing goes from impulse power to warp 9 as though a light switch is involved. Snaps your noggin' back rather smartly. Wonder how tall a gear it WILL pull. Coming off corners above 5K in 3rd has the front end come off the tarmac. I have become very mindful of the direction aimed for prior to twisting the noise handle.
