When i want to pass someone i go WOT and it engages instantly.
2. It isnt just going wot under 3000 rpm. If you go wot in 4th to 6th gear between 3000 and 4000 the CEL will come on indicating MAP out of range or something like that. If you gun it at 1000 rpm(dont know why you would do this) it will go very rich and probably bog. In first gear you are out of that range within seconds..... even after you feather the clutch to get going you usually are at 2000 and it works just fine.
The one thing that i found was i had a crap start once and bogged it(almost stalled) and then went full thorttle to try and get up to speed and it just kind of bucked and bogged. You have to think of it this way, almost no other form of Forced induction can give 4 to 5 psi of boost(sans PD) at 1000 rpm..... there is so much load on the engine at that RPM that it pushes the ECU outside of its known fuel and load tables resulting in rich AFR.
It really isnt a problem at all, only ran into it once as i mentioned.
3. For the dyno on the stock tune we just started at 3200 rpm and it recorded the run fine. It still gets a CEL but the run produced safe AFR's and good power.
Once we tuned we were starting at about 2300 RPM and it has happy to do that all day long without throwing a code. I really recommend a tune for this product.
Hope that helps, keep the questions coming, im the Guinea pig and have had the system for over 5000km now!

Thanks for the input. So if your going to gun it from a dead stop then I'm guessing you'd get rolling so to speak for a moment and then foot to the floor? I'm trying to understand the best technique for utilizing the power from a stop without bogging or throughing a code.
