haha. so swed and I spent like 6 hours tuning the truck tonight, and all I can say is holy fucking shit. I never thought that a crew cab could haul ass like that. It was fucking amazing. Fuel economy is shot...but fuckit ive got power. For any of you that do tune however we ran into 2 issues we currently cant explain. The first is that the truck is not following commanded AFR. We are seeing it drop as low as 10.1 under high RPMS and 2nd to 3rd shift. The other one is we tried to run the monitoring software with the closed loop disabled to gather info, but when we turn the feature off, the software returns" OPEN LOOP NOT READY" error and just stays like that. Thanks guys!! oh yeah its an 04 I-5 Z71 CC :355group:

Not a clue at this part as far as HP goes. We still have somemore to do on it. We have my spark tables down pretty good. But we are going to do more fine tuning over the upcoming weekends. At this point though its enough that from a dead stop, if i stomp on the gas i can spin the rears.

badazz- definatly man...it makes a world of difference...In my case I think fuel econ is going down because at the higher band we hav it just dumping fuel.

yeah dude... swed and i spent like 6-7 hours tuning the truck...driving around...tweaking..driving around again. I dont think you will be able to get philip to commit to that. :shrug: His is a good base tune, but we really altered a number of things. Thats one thing that swed is gonna talk to hi about. I almost think that mine is too firm. That and its seems to really liek OD.

prob not...but i dont know. the thing is in my case it was alot of data logging that we did. and we adjusted from there. I had alot of knock so we had to adjust that quite a bit. Its prob not something that you want on your truck. Philips tune is good, its just that like for anything, if you want precision tuning its gonna take a hell of alot of time. Also this was sweds first I-5...so its a learning project too. That and my tune still is not complete. Its gonna take a couple more weekends to get it better.
