    GTP Injector Tables

    Several have messaged me asking about GTP injector tables. I don't recall the PN for the ones I have in the car right now (they are bagged up somewhere pending my rebuild). These are the off-white GTP injectors.

    I think I found the file, but this is going WAY back in time. The numbers look reasonable and were originals from an ASA tune based on what I remember.

    Hopefully this helps. Sorry to those that have been waiting without much response.

    Cool thanks! The originals files in old posts went dead/missing.

    Not to stir the pot but why is the data conflicting between WS6Firbirds's and Frost's?

    Back in 2013 when I did my head swap and fell victim to purchasing some imitation Bosch 42lbr's I purchased these FAST 36lb/hr injectors. I ended up using WS6Firebirds data.

    Looking at Frosts 2000 A4 data and comparing it to my tune...there are a lot of differences.

    Now I tuned my car and it runs great (lots of hours dialing it in....type A personality..) but I HATE knowing that I may have the wrong inj data.

    Your thoughts? @Frost @WS6FirebirdTA00

    Attached my tune for reference:

    I got my data 2nd hand from another user who sent me an ASA tune with the injectors.

    Curious where the other data is from. I can say the values I used fixed any transient or odd fueling issues I had. I have not compared the two you mention, curious what is different and by how much.

    We will see what Frost has to say. I still have these injectors, so if we can get some first hand info on one of them, that would be awesome

    SHORT PULSE LIMIT is the same at 3.997 for both tunes.

    Are these numbers for the 868 or 811 injectors? I am running the 868s in my 6.0L
