I have a 2013 Elentra Coupe. I looked at different things to get more HP out of her. What are if any suggestions? Would getting a better racing chip, Thermostat, Plugs, or a supercharger set up? The only other thing I'm worried about is voiding my warranty. I have about 9,000 on her now. Not looking to race but just want more power on the top end. I would like to see her get over 135 I think she will but I keep running out of room. I think the only place I could go would be the salt flats. Also does anyone who knows about these set ups think that changing the RPM monitor or REV Limiter would make a difference at top end speeds? I know at the line I take her to the limit through 2-5 then hit 6th and watch the lines disappear. Well maybe I'm just a nut and if i want to go that fast should have bought a faster car but I like my little coupe. She eases in and out of traffic very nicely and rides great. I had the four door before this a 2011 and it was pretty quick and had better suspension. Thank you.
