N20 is a weaker motor, no question about it but with a safe flash, you have nothing to worry about. Either a piggy back on mild settings or a stage 1 re-flash with normal gains, you should be perfectly fine. If you do end up getting down pipe, we can built you a re-flash that will work with basic intake/downpipe but limit torque output to safe levels.
