Well things just took a turn to the worst. I got a CEL last night on the way home. Left and right banks lean. I also noticed that the idle was starting to fluctuate between 500-1000rpm. I resest the computer today. Still idling funny. I think I am going to put the old chip while i still have it to see if this clears up. I sure hope it isn't... That would suck.
As for the MAF and injectors, I'm way ahead of you
I did say I would post the Dyno results
Run.006: New Chip
Clearly this wasn't going to work so I swapped in the old one.
Run.007: Old chip
Still to lean, needs more fuel
Run.008 Old chip, FMU installed (4:1)
Run.009 Old chip, FMU installed (4:1), vac line disconnected
Run.010&.011
Pretty much the same as Run .008
So all in all we're gettiing there. I amnaged to pick up a few more horse power. Still lacking quite a bit. I need to make sure I have all my bases covered for Brian to get this chip dialed in correctly.
Did you ever get everything straightened out ??? What were your final numbers ? Im actually in the procces of looking for a blower for my vehicle and would appreciate any help you could give me. Thxs!
Sorry steeda I've had some connection issues lately. We're still working on the chip programing. This is the fourth chip That I recieved from Apten. We are certainly getting closer. It pulls really, really hard. i am going to try to get it to the dyno this week or asap. It's hard with vacation and the holidays and all to get anything done. So far I'd have to say that it would be in anyones interest to blow thier 4.0 I love this truck more and more. I'll be posting more numbers soon. The only problem that I have been having is the tuning. I am still getting some WOT ping which will hopefully be resolved soon. Man does it pull hard. I am going to get in touch with Doug from 4.0 performance to see about making me some heads, cam, ect, ect. Then we'll get to witness some mean track numbers.
