    single turbo tune questions

    first I want to say I am new to hp tuners and have lots to learn. I am in final stages on this project. Its a f body with a 6.0 single front mounted 76mm turbo, liquid intercooled. I have 83lb injectors with a versa fueler.
    Here is my start up program.Attachment 8066
    I started the car tonight. It starts and Idles fine the long term fuel is in cell block 9 is taking out -15. when I snap the trottle it hesitates on the wide ban a momentary lean situation occures. I have a ford 90mm throttle body on it. I was wondering where do I increase pump shot fuel? what table? I also am using a 2001 truck computer and software. I converted it to a 3bar set up so I think I did that right but if someone doesn't mine taking a look at every think I would appreciate it. also If anyone has done a file like this so I have something to compair to I would also appreciate that as well.
    I have a few other thing to get button up on the car before being able to drive it. I am shooting for 1000hp. It should be there If all goes well.

    Thanks.

    I guess know one can tell me the answer to my question. anyway I discovered that the minimum trottle position is 7%. Its a ford tps so I will have to do some modification to the sensor so I can adjust it down. I feel this may have something to do with the hesitation off Idle. correct me if I am wrong but I think the transient fuel tab under transient fuel qualifications is what the answer was to my original question. It is set for less that 3% throttle is when it is in effect.

    Can some one answer why is there nothing under the accel enrichment tab. also the is nothing under the speed density tab. I am just wondering if I need to do something more to be in speed density mode. I maf is a 0, copied the high octan table over the low. Left the code sets allone.

    Thanks

    You have nothing in those tabs because there is nothing in your OS for them.

    On an ETC car, your idle TPS is seen by the computer as 0%. Transient fuel can help, you need to set that up based on your injectors. A scan may help...

    The set up is not ETC. I have got a 90 mm Ford trottle body. Is there a way to change the os to eliminate the stituation. And it I change the os, do I need to pay more credits for the 3 bar? thanks
