here's my mod list. Can i run stage 2?
 

ETS V2 Catback
Test pipe
ETS 3.5" Intercooler

I wasn't sure if the lack of a down pipe or the addition of an intercooler would cause problems

thanks

I'm no expert. I'd say yes with a huge BUT...

Without gauges (boost & AFR mainly), how will you determine if somethings wrong with the map? Don't take for granted the plug & play features of the cobb ap. I've learned (luckily not the hard way **fingers crossed**) that it's best to stay safe rather than being sorry later $$$$$$$

Sorry to sort of beat around the bush on your question, but I always recommend a tune in this sort of equation. Yes, it is an expense, but a very worth one.. I would wait until you can get the car dyno tuned by a reputable tuner, and then do your mods at that point in time.

That way there's no questioning it. A safe tune, and picking up some power along the way. That's a win win.

From what i have been reading and been told by a few tuners, you should be able to run the stage 2( just watch your knock and i would def. get some gauges to watch your AFR) with what you have. The inter-cooler and the tune SHOULD be fine, but you won't get the full benefit out of it without a pro tune

test pipe = stage 2

Umm....yeah buy a dp it makes a big difference
