I don't think it helps that I've been throwing fuel upgrades at it but haven't messed with anything except the exhaust. I'll change out the air filter and let you know how it goes.

 

Sounds good! hope thats the problem if not let me know ill help ya out.

 

Thanks for the offer man, I've got the next two days off then going on a 6 hour haul trip for the weekend so I need to get her in shape to haul horses up a few PA style mountains, nothing like you guys have out west.

 

Here the mountains are burnt like bad kentucky fried chicken. But ya if you need more help you can shoot me a PM and if you want it I can give you my cell number and we can go over it if she continues to have issues. I would like to ask if you have an EGT guage hooked up and if you do what is it reading when you hit overdrive.

 

When I cruise down the highway usually 500-700, if I see it hit 1000 I get out of it...my EGT probe is post turbo right on the elbow above the downpipe.

 

500-600 is normal for post turbo but its 700-900 pre turbo, so your pushing some fuel
