Basic tune for vortech supercharged lt1
hello all,
i have a 95 lt1 a4 vert trans am. I picked up a vortech v1 supercharger waaaayyy cheep.
I got it on the car but as of now am being pretty easy on it.
i am looking to “tune” the car a little with tuner cats. (I am a total beginner in this space)
car is basically stock it has 3” car back, vortech v1 supercharger fmu, vortech in line pump booster,crane cam hi-6r ignition. Boost gauge (about #5 is all I’m putting out now) wideband.
I’m in California 91+ is what I’m running,
timing is set to -1* per lb boost
(No intercooler or after cooler)
I do have 60 lbs injectors NOT YET installed still need to upgrade the the fuel pump. (where are y’all getting the walbro pumps at or a good price)
are there any things I should chance in my stock tune to help make it a little safer, it will be a few months before I can pick up a fuel pump for the injectors.

Photos would e great if y’all are useing c.a.t.s.

thanks in advance.

i picked the car up for 500 bucks runs pretty darn good. I will in a year or two build a motor for a little. just looking for some basic tune tips so I can enjoy driving the car on weekend for a while with out it just blowing up.

If you already have the software, a base tune from Solomon is really cheap. He could dial you in, then you could fine tune it at your leisure.

 

Thanks man I appreciate the help

 

You're welcome and good luck! Keep us posted with a dyno sheet or a drag slip when you get it where you want it!

 

He's getting some good input on parts and tuning on the ltxtech site.

 

I absolutely am. I am a little overwhelmed lol. However I am taking it all in and getting great info. I absolutely already contacted LT1 PCM Tuning - Tips & Tricks for DIY Tuning! for a general set up. I cannot tell everyone across all the forums how much I appreciate all the input.
