Need some help
 

I've got a 99' 150 4x4 with a 5.4/auto payload package (7700) off road package with 3:73 posi which now has 110,000 on it. I've put headers on it, high performance COPS,new plugs, K&N FIPK, edge maf (put the orginal back in now as I thought that was the problem) and I also have a Flow master 3" into dual 2.5" exhaust.
It now runs terrible- the bottom end is just gutless and then at about 2500 rpm it REALLY comes on but on the low end or if it gets a load (like going up a hill) it acts like it has a miss or bogs way down. I've had bad cops in the past (owned it since new) and I really dont think its that because it idles smooth ect. ect. unlike any symptoms it did when I had a cop go bad. It runs fine when your not on the throttle (like when my wife drives it- I have a little heavier foot then she does) But if you really get on it, it falls on its face. Now that its cold (MN) it runs pretty good all the time- colder denser air seems to help it anytime.

I ASSUME I need a tuner to program it for the mods I've made-BUT which one? Its mainly a daily driver- But I farm so it does see some fairly heavy loads from time to time- the biggest being my pulling tractor at about a 9000 lb load.
Any help in the right direction is greatly appreciated-I'd like to get something bought ASAP.
Thanks
Rob

Bill can definitely set you up but you'll have to wait until they get back from their vacation next week. :thumbs up yellow:

Well I've been messing around with this for about a year- for some stupid reason- so I think a few more days will be fine.

Thanks for the vote of confidence!!!

Do I need to wait for a reply from bill here or just call?

You can try calling them to get the info you need and to set up an order.

The three of us have pretty much been on the phones constantly since noon. Did we speak to you?

yep- I talked to corey right in that 4 O'clock area-
