    I'm rocking the TMIC for as long as possible.

    On a recommendation to delete SWAS to fix and AFR issue I was having, I did the ol` switch in the blue wire trick. It worked. Again, I do NOT tout these as gospel, but it`s usually pretty close, and I`m pretty happy at this point (still some fine tuning to do to get the numbers just right but it`s getting there):

    Looking good! I have much to look forward to. If it stops raining tomorrow, I'll find out if the tuner fixed my fuel cut issue. If he did, I'll be off to the e station soon!

    well....something is definitely awry. Ripped a 4.7 60-100 time and the pull felt great so I ran VDyno when I got home. Here`s the result:

    It was pulling like a freight train, but I can`t say it was pulling like 494whp. At the same time, the RPM and Vehicle Speed curves are VERY linear (not a sign of clutch slipping). I mean, seriously, where would another 100hp have come from? I`m sure there`s some explanation, but it`s fun to look at :-D

    Might be slipping tires or clutch. Your torque is past the edge of what's safe on stock block and clutch.

    Oh I know man. Once I have an accurate, real number I`ll probably work on flipping the tq and hp numbers to get tq down to around 380 if it`s actually above that. I`ve got an engine sitting at the shop getting built as we speak, and it`s getting a new clutch as well when the engine goes in.

    Clutch is my guess. Torque actually tends to descend some toward redline, depending on the tune and turbo, and I know that PSSes are good. I only have 390whp and run a 4.6-second 60-100. I think something went wacky with your graph--something about the way it looks.

    I`m gonna guess a road anomaly (a rise/dip in the road). I graphed rpm and speed and it did the exact opposite of what clutch slippage would have. A slight dip in rpm, very brief and no perceptible change in vehicle speed. I recall encountering said road inconsistency as it`s right about where I let off the gas.
