Start with your supercharged file first.

Just get the injector cal from the spreadsheet in the stickies. Put in your injector size, set the engine size up for 6L.

Post your Log (.hpl) & Tune (.hpt) files if you want some more help.

Looks like a classic MAF tune on a supercharged application. You won't be able to do that with your APS TT. 2 bar will be mandatory.

You will probably have too much spark in the higher g/cyl areas of the main spark table. The TT's move a lot of air efficiently.

Need more info on the injectors as well.

running 60 lb injectors, boosta pump, walbro hi flow pump..let me know if you need anything else..thanks

Here's something that should get you started. I turned off the MAF so don't boost it until you apply a 2 bar cal & 2 bar MAP sensor!

It has the correct injector flow rate so you shouldn't need to move it. It has a "startup" VE table which may be wrong but will get you started, idleing and light driving. NO BOOSTING IT WITH 1 BAR!!! LOL
