I just purchased the 1.1 box and still waiting for it to come in, my question is what curb setting is best for towing witch one will give boost a lower RPM?
It's all very relative.
You'll definitely want to make your own curve as you tow and figure out what works best for your load and motor.
Thank you for the response this is all new to me! Is the install pretty simple? I order the one that's fully assembled
yeah, nothing too hard about it... hardest part is getting the turbo to physically fit, downpipe, etc
