Does it work with our trucks at all?

 

anyone???

 

ok thanks

also, i have a 98 suburban with a 454 in it, will it work for this as well?

 

Yes it does. I have autotap and downloaded an eval version of EFIlive. I like the way EFI is set up better plus you can temporarly change certian perameters while you are driving. That makes tunning a whole lot easier.
