I have spent an unhealthy amount of time searching and reading through old threads….and I'm still unsure if I want to try an aftermarket "cold air" or not. I do not intend to ever swap intake manifolds, and really don't envision doing any other performance mods. I have full exhaust and a Lund tune, this is really the last thing I'm contemplating from the performance department.
I like the way the JLT looks, and this is really the only intake I'm considering. I am well aware that the performance gain is a never ending debate. I am also well aware that the intake air temps can get considerably higher. How much effect this actually has on performance is another never ending debate. I also realize these kits are significantly overpriced for what you get.
My main question is about drivability. I asked my tuner about getting a revision for an intake and I got the feeling that they may have been trying to advise me against it without coming out and saying that. I've always thought a tune revision for an aftermarket intake would simply be copy and pasting in an already well know MAF curve into the existing tune. They hinted that it may not be that easy, and fueling may need to be "massaged".
Even from day 1 with this car completely bone stock the throttle has felt a little weird at times (especially when not completely up to temp…holy cow it is bad when cold). None of the mods I've done so far have really changed that at all. The throttle still feels a little goofy but I guess that's just how it is. What I definitely don't want is the drivability to get any worse.
So my biggest question…when done right, does drivability and throttle feel suffer with an aftermarket intake (specifically a JLT)? My car sees over 30* at WOT and my fuel trims are almost always within 2-3% so I feel the tune is as close to dialed in as it can realistically get. If I can get an equally dialed in tune with a JLT I'd be happy. I'm wondering though if that is a realistic expectation?
Any thoughts?
Thanks
