do i need a tune? please help

zuperman 370

hello all i hope that someone could help me out with this, the current mods that i have on are amuse stti exhaust, berk hfc and r2c intake, the guy at the shop today told me that my car might be running a bit too lean with all those mods without it being tuned, and that if i continue driving the car like this my engine could blow at any second, no i havent gotten a tune yet because i still want to install some more mods, and then have my car tuned, so my question is is the guy trying to B.S me just to tune my car or is there really a possibility of the engine blowing up if its running this lean, sorry for the noob question and if this is a repost, just hope u guys can help me
