My Cobb AP is on its way and i'm planning to install dps today. Is the car going to be rough, shake, or just drive normal with the cel light on the dash? Thanks

It'll be fine to drive around with the CEL. I drove around with catless DPs on stage 1 v203 for a couple weeks with zero issues. You should go ahead and order a FMIC and intake from jeff@topgearsolutions, stage 2+ is more than worth it

VSRF is coming out with there "inexpensive" FMIC in the springs, I would hold off until they released more info.

Just my .02 cents

I already have the fmic and dci. Dps are in. Thanks guys

How many miles are on your car? I would HIGHLY suggest you go ahead and change you plugs if you have over 20K miles. Stage 2+ requires the car to be in tip top shape.
Btw, enjoy the Cobb AP and drive safe

It's at 48k on 2nd set of spark plugs. I changed it about 20k miles ago. Is it due for a new set?

I'd say do it. It's a super easy DIY, if you did the DPs you'll have no problem. It'll only cost you a little over $100 for plugs and socket. These cars are HARD on plugs(even more so when tuned) and respond really well to changing them every 20K. I know of a couple people that have gotten into the habit of changing the plugs every 10K miles.
