I am considering whether or not to add a little "Mojo" to my '04 Crossfire LTD by adding the Needswings Dual CAI, and a Eurocharge ECU tune. I have studied the specs and the expected performance gains, and while the added horsepower and torque are not to be dismissed, I wonder if the gains are noticeable (and legally usable) enough to be worth the investment? I have read some threads here in which members praise the improvements, but are the gains really good enough to influence the "Wow" factor? Can they make a noticeable and worthwhile improvement to the performance and handling. I would be interested in hearing from the folks on this forum about their opinions and experiences. The more specific the explanations are, the better (e.g. throttle response, mid-range RPM/MPH gains, ease in manual use of 1st gear and beneficial downshifts, etc). Would like the hear the "Good, Bad, & Ugly" as well as opinions on the value of the money spent for the gains obtained. Thanks!
p.s. I have been a member of many automotive forums, and I have found this one to be the friendliest, most helpful, and expert of all.
