[QUOTE="Juiced46, post: 12292879, member: 11519"] So I was going through some old videos on my computer of my Cobra and found a clip when I had the 6 speed in it (back in 2008). I see alot of guys on here post when they put a 2 step on their Turbo car they can only build 2-5 psi. You can build boost with a stick turbo car and a 2 step. Just adding the 2 step will not cut it most of the time. The tune needs to be adjusted for it to build boost properly. My car after adjustments I was able to build between 10-15psi on the 2 step. See video below. What you need to do is. Datalog your car on the 2 step. I had the 2 step set @ 5200 RPMs. This isnt for the people that want to launch soft out of the hole, you have to have some balls :beer: You need to watch load while on the 2 step and adjust from there. So basically in the SCT software I adjusted timing based on load and RPM. The adjustments were made from 5000 RPMS and above. This will not affect WOT or part throttle, unless you are driving half throttle above 5k which is crazy. I ended up with -5 degrees of timing above 5000 rpms to get it to build up to 15psi. I do not remember where load was on the 2 step. I believe between 1.1-1.5 while on the 2 step. This is where your datalogging will come in. Put the car on the 2 step, watch load.
