has been in my car can tell you that lag is not a issue with my 3071 set up. The turbo housing size in Joels car with his manifolds are costing him some lag. The size turbo wheels is not a problem with the proper housings for the application and short manifolds. Here is dyno of my car on boost alone (450 RWHP at 4500 RPM) (625 RWHP at 5000 RPM) You can see there is not any waiting needed.....No flat spot waiting to come on.....It just keeps climbing. I also started the pull at 3000 RPM or it would show even higher power at the lower RPM levels. For my car there is not a point in starting lower as my car has a built auto with a 4000 Stall convertor. It can cruise around fine at low RPM and I have a triple disc lock up to keep low RPM on the highway. What ever speed I floor it the RPM will be at a minimum 4000 RPM or higher, so I really have no lag.
