got my gtp tuned

[Venomous281]

The weather finally cleared up and I was able to go get my gtp tuned. I made a 4" fenderwell intake, catalytic converter was removed and pulled out the 160* and went 180* car has ngk tr55 plugs. I felt a huge difference all around and I love that the car shifts more firm. Next step is headers, 42lb injectors and ls6 springs. My injectors were at 122% duty cycle and I found out my car has 3.29 gears.

You have a comp g then. It should have paddle shifters

[Venomous281]

It doesnt have paddle shifters and I checked the rpo and it doesnt say ws6. In the hp tuners my ecm said 3.29

[dsmuts]

I think they all say 3.29 not sure though.

[wa04compg]

Yeah I have a comp g and is says 3.29 as the calculated gear

I think they all say 3.29 not sure though.

They do. My 2000 GTP says 3.29, others number are plugged into the PCM to make it the 2.93's gears.


And how the hell can you IDC be at 122% with little to no mods?

I have 3.6/headers/intake etc etc with stock injectors running a max of 75 IDC on 93 pump gas. I've never really had to adjust fueling either.

[Venomous281]

I dont know why but they are maxed out. I didnt really want to put bigger injectors but I guess im gonna have to.

[Fivefingerdeathpunch]

Or just fix the tune.

[wa04compg]

Sounds like a tune issue to me

[txslow6]

How much timing are you running?
