New TBI owner in need of some help....

[Fast355]

I really hate hearing that. He never mentioned that it could be as simple and cheap as moving a vacuum line (which mine was located on the back). That was 450 bucks wasted....

Don't get me wrong, the factory style unit is better and the original design holley injectors are known to cause issues, but there is a known driveability issue when the MAP vacuum is attached to the rear port. Where the port is locate is right in the IAC passageway. As the IAC opens it causes a loss of vacuum signal to the MAP which cause the engine to run rich. When you open the throttle the MAP does not change much and the engine develops a lean bog from lack of MAP AE. The problem is noticeable enough that from my experience I can see it in a Datalog alone.

Ok, gotcha. It is a little relief to me knowing that I now have a better tbi.
Any idea of what could be causing my issue. I ordered an ALDL cable off ebay from a Red Devil River. I also downloaded winaldl last night on my laptop. I will be reinstalling the tbi tonight and hooking a computer to the vehicle. Is there something I can do to post maybe a screen shot on here to help you guys help me?

Sorry simadownow6988, I can't really help you much as I'm a newbie, but I just ordered that motor your running and am excited to see someone else with the same setup I want to run. I still have my stock throttle body and need to upgrade. If you want to sell that Holley, PM me a price. If not how was your experience with TBIparts.com? What all did you buy that added up to $450? I have also had a frustrating experience with Brian at TBIChips.com, but lucky for me I found this forum before buying anything more than the fuel pump. The guys hear have told me that winaldl is nearly obsolete and I should download TunerProRT, which I've done but can't play around with it til I get my motor. Have you bought a chip from Brian yet?

[simadownow6988]

I did buy a chip from him. He supposively made me a custom tune for my specific setup. I let him know everything about what I have.
Tbi parts has been awesome! I have the Holley still. I am considering selling it.

If you don't mind, what part of AR are you from? I live in Searcy.

Great to hear on tbiparts. I am about to buy new setup for mine as well and was looking at going with them.

[simadownow6988]

Well it looks like I have been screwed with this chip. Can anybody help me get a correct chip in this thing? I just want it to be right...
