mine has it on the door.

 

Not really a good indicator, some do, some dont, some have been changed.

When I had my e99 truck that was the first thing I changed.

 

Can you use any of the good turbos,injectors, programmers ect .It sounds like the motors are pretty much the same just the bolt on acc are different ? I noticed on some of the upgraded stuff it says not early 99 .
Thanks

 

most of it you can. about the only thing i've found that will not work on the e99 is turbo stuff. like there is no ported compressor housing for the stock e99 turbo.

 

The E99 turbo uses a different pedistal and all that so You would have to swap everything over to the Later stuff...

Injectors can be used throughout all 94-03 powerstrokes with the right programming to run them.. Most programmers/chips are PCM specific but can all be tuned to work on whatever vehicle you are running...

 

that's what i meant with the turbo stuff. but thanks for expading on that.

 

i put the wicked wheel on my 01 when i got my truck a few months ago. doesnt sound different from what i can tell, but it doesn't surge like the old one. if yours doesn't surge, i wouldnt worry with it. to be honest with you, i believe my fuel milage dropped slightly witt the new wheel. idk if thats possible, but as some of you know, i truck for a living and check my fuel milage EVERYDAY. on that not, my new chip got me my best empty mpg ever!!! 12.84.....thats 17,000lbs empty boyz and gurls.....!!!..

 

why didn't you just get a ported compressor housing?

 

How much better is a 17 degree than a 15? whats the difference between the injectors? Whats the difference in the codes? for the injectors?
am i able to use the up pipes off a 99 in my 97?
also is the turbo any different? intercooled?

 

No you can't just use the uppipes off a SD on your OBS...
AA/AO have 90cc of fuel
AB's used in E99 have 120cc of fuel
AD's use in 99-03 have 140cc of fuel
17* is better than a 15*
