Were you adjusting the VCV at the IP, or the modulator at the transmission? The VCV setting is not really adjustable, it should be set to factory spec... I dialed in the modulator.

With my stock pump maxed out, I never got full throttle smoke, ever. As long as you have enough airflow, you won't get any.

Not bad at all! Does it improve any with light power braking? My current setup launches a LOT harder if I powerbrake for a couple seconds to get the boost needle off zero before letting off the brake & pinning the throttle.

Yeah, I experimented with this too, and in general it's not worth the hassle. I tweaked the tranny to upshift at more like 4900-5000 and called it good enough. I had previously done some testing with manual shifting and IMO, the improvement in times (if any - it was tiny) wasn't worth the hassle.

Casey and myself both ran into problems when going past 1.5 turns on the full load screw. At 2.0 turns it wouldn't always return to idle, had starting problems, and had all the power with half the pedal travel (and nothing more happened when you used the last half of the travel). Adjusting the linkage rods was also a real pain. That was one thing I really liked with the 6mm pump... no idle problems, no start problems, no linkage problems!
