    Gen 3 swap data log help

    Hello everyone,

    I am new to HP Tuners and I have been doing some research into how-to via videos and using the platform by reading the forum. I have had to do a lot of changes to my ECM and how its setup do to the previous person I took the truck to changing a lot of parameters and values. I ended up buying the software myself and giving it a try. By using the compare file function in the editor i have been able to get the truck back to close to factory settings (Best as far as my knowledge). That being said, I would like to have some more experienced tuners or users take a look at my data logging and see if I'm on the right track. Any and all help is appreciated.

    blindsquirrel,
    Thanks for the reply. I was able to use the link provided to further research and compare more files to my setup. I think I have got a good baseline to start from now. A little more about the truck: It is a 2004 5.3 from a Tahoe in a 1983 C30 dually. I have kept the 1983 SM465 manual transmission and the truck itself is stock other than the 5.3. I'm using the factory 2004 flex fuel injectors with a returnless fuel rail system and a Corvette style regulator/return inline on the frame. The fuel pump is a Holley Sniper unit that pushes 315 lph. I'm also using the early LS Corvette exhaust manifolds for clearance reasons in the engine bay. Is there anything else i may need to address in the ECM or make changes to in order to optimize vehicle performance?
