PHP Gryphon Up grade or change the CIA?
Good Afternoon to all,
I have been on other forums seeking guidance and gotten kicked around pretty good. It seems all those members like to do is talk smack & run down other peoples stuff. That does'nt appear to happen here. But just in case, please be gentle with me. I have a 2008 F-150 5.4 crew cab with an AEM brute Force CAI (I know, brute force, what a joke), Edge Evo with canned tunes, Gibson cat back exhaust, Pro-Comp lift with 35" tires, 4.56 gears. The problem: With the Evo set for tow (stage 2) and all perameters set to match up grades, the truck cuts out at approximately 70 to 74 mph. If I get off the gas and roll back into it, it cuts out. Once I get through that window, the truck runs great. No codes. Set the Evo back to Transmission (stage 1), all perameters set to match upgrades, truck runs like a champ!! The natorious lean condition, right? (and the call me dense). Finally, my question. I have read that PHP has dyno'ed CAI's and found only 2 that do not cause the lean condition. What would be the recomendation of the kind folks here who have experience with PHP? Upgrade the programer or the intake? I believe the cost to be almost the same. Thanks, Redshirt Last edited by redshirt63; Tue, August 9th, 2011 at 11:03 PM. |
