Re: Time for upgrades,need advice
Single intake will do you just fine unless you want the looks of the dual.
I would wait a few weeks for the new tune/ pulley deal that Eurocharged should have coming out. Actually, I would go ahead and see if they will allow you to prepay because if they are like the C3 pulley, they will be gone in no time.
Speaking of gone in to time- go ahead and order a new IC pump.
Heat exchanger should be last on the list unless you plan on racing.
