I have a 2011 GrandSport Convertible, stock with the exception of Corsa intake and Corsa axle back exhaust add-ons...also installed a new throttle body last year, but it was OEM. This is a daily driver for me for the next 2 years until I can upgrade to a 2015 or 2016 Z06.

So my question is that I am considering a dyno and tune, as well as possible X-pipe and/or drilling manifold. What I really want to accomplish is a 50-100 horse boost on the vehicle if possible without spending too much cash. Is this reasonable?

Considering the mods I have already done, what are some recommended options that can be done for around $1000-$1500? Just looking for some fun increased street performance.

with a long range plan of getting a Z06, I would keep the GS as near stock as possible, maximizing resale value.....2cents

Headers ,Cold Air Intake and a Tune will get you 30 to 40 hp and a huge increase in the driviblity fun factor as the increase will be across the board and not just in one specific rpm band especially in a daily driver . I love the power my car makes now

100 hp is going to cost you a lot more than 1500 ... cam , heads and always the trade off of a bit of street manors

Headers,mid pipe and tune is an easy 40
Have fun
