Help with Vortech supercharger set up map

Post by fennsbayparts300c »

Hey everyone needing some help here please !
long story short
My car was a 300c 5.7v8 hemi wanted more so
Since then I’ve added the srt8 6.1 v8 all running gear
rear diff subframe Propshaft gearbox pcm tcm ecu
with a vortech v3 supercharger
it’s also got uprated fuel lines booster rails and injectors
The engine will run but takes a lot of turning over to fire runs rough misfires
Will not rev past 2,500 in limp mode at a guess
Codes I get are
129 barometric pressure to low
300 random miss fires
Crankshaft position sensor a circuit

Now I never got the predator tuner with the engine and box! So assuming it’s running the standard map and not enjoying it
I have a i3 DiabloSport but this only gives me a standard tune
Where can a get the “predator supercharger set up tune”
How can I get custom tunes on my i3 to my car

Standard Speed Density Table mapping for the Hemi (naturally aspirated) will not work with forced induction. You need a custom tune for the supercharger. You can get a email custom tune (e.g. HemiFever Tuning) or take the car to a dyno shop that is experienced with tuning supercharged Hemi enignes.

Thank you I have been looking at the tunes on Hemi Fever for a while - ordered one this morning and have received an email asking for some files from my diablo that I have now sent so fingers crossed!
