    Many tuners charge for a limp map.

    True. But a limp map will be cheaper than part install.

    My argument is that he is not maxing out turbo with that tune. With a 300+whp tune on a wrx u (or any vehicle) u must address the weakest link/ bottleneck first. With the 3G, it's the intercooler and fuel system rather than the intake. Now if u maked the vehicle out without the intake and then were able to squeak out more on the aftermarket then it would be more conclusive. But u don't need an intake for any of the ots maps and I am still not convinced that it is a restriction for the sm's goals. But he wants it and that's cool, it's all about preferance. Thx for the link though, I appreciate it.

    I'm aware of the restrictions of the stock TMIC and BPV. I have to limit the boost I target on tunes because of them.

    You asked for before/after dynos of an intake; I provided you just that. You can see in the plots that the boost wasn't used for the additional power. I wouldn't run 19-19.5PSI on a stock WRX TMIC of that year, but the gains are not boost-related, so that's somewhat of a moot point.

    People tune cars differently. I would say that if you're already getting a custom tune, I don't see harm in spending $250 on an intake for some additional power and some noise.

    The shop should send you a base map for the modifications. If they ask for money, verify it's a deposit and it'll go towards the tune final cost. If they're going to charge you full rip after you pay for a base map (so you can use their services), send them a picture of your ass with "Kiss This" written on it and find a new shop.

    I guess I worded my reply incorrectly. what I was getting at was this: how can u tell which power gains came from the intake? That was my point when I talked about the fuel system limitations. The SM in the link added fuel system upgrades in conjunction with the Cosworth intake system. Again: I am not trying to spark a heated debate about cai's but rather to gather information for anyone reading this thread (including myself!). I suppose there isn't much out there in the way of isolating individual power upgrade's actual outputs, as its not really time/cost effective. Thanks for the info and the quick replies.

    I couldn't agree more.

    I answered that question for you, already.

    I typically see between 10-15whp peak gains, with similar or slightly more at redline; you will not see the massive (25-30whp) redline gains in the link I provided with stock injectors, as you'll need to dial things back a bit to keep IDCs in check.

    Agree to disagree then. I don't think you are seeing the variables here...stock airbox on my 11 and turbo is maxed...no more cfm will help there...bottlenecked. if you have anything more technical than 'what I have seen' I would love to read it.

    Real world performance trumps internet theorizing, every time.


    The turbo might be a bottle neck, but if you improve the volumetric efficiency of your engine power will increase regardless.
