Ive got a '08 STX 4.6 and am planning to add a Airaid CAI and a Borla Catback exhaust. Ive heard a couple different thoughts. Tune or not. Is it needed? Please give your imput. Thanks

Some say the CAI will cause the truck to run lean but I've had mine in for around 5 months and haven't had an issue I got an edge evo for the extra power it was the best 200 I ever spent mounted a 2008 XLT 4.6 2wd Screw

I agree, a programmer will really wake your truck up! I got my used Edge Evo for $125 with pod. Best mod for any truck owner.

I say tune it....but then I may be slightly biased as well. :-)
