Are you going to lock your converter on the dyno?

How many pulls do you get?

What do you plan on doing different for seperate pulls?

 

they charge $70 pre hour and will go in 1/2 hour intervals after the 1st hour.

i think i can get 4 runs in an hour but i can go 1 1/2 if it takes that long.

planing on a NA run
then a 150shot run
then a NA run with the exhaust pulled after the Y
then a 150shot with the exhaust pulled

might have to wait for the bottle to warm for the 2nd nitrous run but that should be the only hold up.

i got EFI live PRO and it is cool as hell, i plan on locking it in 3rd and locking the converter, i am told that is the best way to do it if you can. i tried it in the drive way and driving around and it really works. if i lock it in 3rd while not moving it goes into 3rd and then if i lock the converter(while not moving) and it kills the truck just like it should.

my tune is not great at all, edit is messed up and it is killing me. my a/f ratio is around 11.8 na with 24deg of timing, i think there is more power there with less fuel and more timing. then my nitrous run is WAY rich for most of the run, like below 10-1 but as high as 11.5 for part of 1st.

anyone want to throw out some guesses? this is on a mustang but they have it calibrated to read dynojet numbers, they said they wanted the good dyno but most people want to hear the dynojet numbers.

 

NA---250

150shot---390

NA uncorked---270

150 uncorked---425

 

What timing do you run on the 150 shot?

So is the 11.5 afr in 1st the lean spike you were talking about?

 

You have a wide band right? Does the dyno shop also?Would be interesting if you can compare the two.

 

Told ya ... good luck .. and be sure to give us the results.

 

still geting 24deg with the 150shot wich seems to be ok expecialy since i am rich, the lean spike is anywhere from 15-1 up to 18-1 then it drops to 11.5 then about the end of 1st it goes WAY rich, could be COT but i am not sure.

does that seem like too much timing for a 150shot, the car guys run that much and more like 28deg na.

 

I don't know anything about nitrous timing. I'm just comparing it to the 12-15 degrees I see with my setup. How much timing did you run on your old truck?

I knew I needed more timing but maybe I need alot more??

 

with the whipple i got something 12-15just like you, i think you can get more with the intercooler and i might be running a little too much for a 150shot.

 

How is the best way to raise timing? Do you just raise the retard limit or change timing in the tables?
