My son bought my 05 sti which I loved. When he decided he wanted it 5 years ago, I broke down. Im now a new owner of a 2010 gsr that Im going to be starting the mods. I just bought a cosworth intake from a member here and I want to put it on, but am going to wait for other upgrades, downpipe, midpipe and boost controller before its tuned. Will it run fine with just the intake? I also have ets exhaust axel back.. thanks phil

 

Personally on all my past cars I've only done a catback without a tune.

Then as I did on my evo I had over 15 parts ready to go.

I installed them all at once and got tuned.

Hope this helps.
