hey yall im either gonna be getting the MAFTpro unit or hptuners as my next mods- i like the MAFTpro because it is a datalogger and has a/f ratio tracking.

i have the stock 4.3L injection system so i cant upgrade injectors without going full standalone.- so right now im running an FMU, and later im gonna going to an extra injector set-up-

1.)i was wondering how HPtuners would react with the FMU or extra injectors-

2.)would the tune stay good as temperature and humidty change?

3.) does HP tuners come with a datalogger or do i have to spend ANOTHER $150 for a datalogger?

4.) anyone with experience doing this?

 

You can do a custom intake manifold so you can use larger fuel injectors to fuel your V6.

They do make a V6 marine intake as well.

HPtuners has excellent data loging capabliles and way more tuning options than a MAFTpro.Are you running a throttle body injection or what?Why not run an inline fuel pump and bump your fuel pressure?
