He has a point about both parts. First there wont be a big enough difference between the 87 and 89. They will probably be almost carbon copies of each other. Also you never know when you will get put in a situation where you have to hook up and go. But if you dont want a custom tow you can just leave it at canned tow and save the money.

In the door jam on the driver's side there should be a yellow and white sticker. There should be an axle section and it will give you something like H9.


....And it looks like 88 just posted the same exact link I did so I'll get rid of mine.

The 87+89 are the same tune with the timing bumped a little one way or another. It's when you jump up to 91+93 the AFR tables+strategies also change again.

so i just looked at the sites you sent me bro and it says H9 what ever that means? so how do i figure it out becuase you said it supposed to say 3.53 or 3.57 somthing like that right?....

but also what do you suggest i should get on the level tunes? if that what your saying

1) 87 tow
2) 87 performance
3) 91 performance ????

thanks for all the help you guys!!!

ohh and guys if this helps at all this is what i was looking at

[Longshot270]

H9 stands for for the 3.55 Limited Slip
And that lineup you have looks good.

[Unleashedford]

thanks a lot you guys for all this help, few more questions if you guys dont mind

it also says flow rate: stock mod what do i put there

and also

on the bottom it says

Lift: in__ ex__ DUR: in__ ex__SEP__

underneath that it also says stall RPM or does that go with the torque converter

[Power Hungry]

The section on lift is in regards to modified camshafts of which I'm sure you don't have.

Stall RPM is related to the converter and again, is only for modified components.

Basically, if you didn't change it or you don't know what it is... leave it blank.

Take care.

Thanks Longshot!
I was gone to the kid's BB games most of the afternoon into this evening and more to watch tomorrow!

[Unleashedford]

hey bill or anyone whos knows this information


when ordering the custom gryphon do you guys ship out the gryphon right away with canned tunes..and later on email the custom ones so i can upload it or wait till your done with the custom tunes add it on then ship it out?

[Power Hungry]

If you have any way of determining the calibration (HEX) code, we can send preloaded. In most cases though, the customer doesn't know what the code is and custom tunes will have to be downloaded later.

I can give you a call later today if that's okay. I was hammered on phones yesterday as Corey was out sick and I must have missed 100 phone calls.
