Engine/Transmission (1998.5 - 2002) Haisley Anti Defueling Device

[rowilson]

Hey guys I was wondering if anyone has used or is using a Haisley

A. D. D. on a fairly stock truck. My truck is an 01. 5 3500 with a BHAF,

4" straight piped and an automatic. I spoke with Patty Haisley and she

was VERY helpful and informative with my questions. I would like to

add some power to my truck but not wanting to really go with a EZ

or something similar. What do you guys think of this part that have it?

The price is really reasonable and if it delivers the extra punch I'm

looking for it would be well worth it.

the add will not add any additional fuel it will just prevent fueling above stock level

Just outta curiousity, why don't you want an EZ????

the A. D. D. is to help with bigger injectors, so that the computer does not see over 21lbs of boost. you might as well get a ez as it has built into it.

It's not so much that I don't want an EZ because I think I do. This is my first CTD but I burn chips for Buick turbo cars and know a fair amount about them and know what is real and what is hype and I know not to jump into making or buying mods that aren't what they claim to be. In the Buicks we burn a new chip for whatever injectors and other mods you've made and pop it in. With the CTDs it's not as easy as we're all seeing from the Mad ECM from Marco. With the Buicks I had the good fortune to be friends with a GM ECM programming engineer and although he had the calibration documents to make changes to the ECM programming he really didn't use them since he wrote his own code. His stuff is and was the most advanced chips on the market even today. But enough of that. For me it's the cost at the moment. Making upgrades in small affordable increments. First changed out all fluids to Amsoil and then I added the Marine Fleetguard BHAF and a straight piped mandrel bent 4" turbo back exhaust. Now on to gauges. Pyro, trans and boost.

I'm running the Haisley ADD on my 02 with Bullydog 2 injs. The device works great. I needed a new injector pump due,(I Believe) to the comp box. So I sold the box and kept the injs. Jeff
