What about your config file, the transmission tune, etc?

I bought my HPtuner for my C6 Corvette and I use it to scan and make adjustments at the track but I would like to use it on my truck. Right now I have a PPE tuner and I run on the #4 ( 160hp )...

No

Tried it and the surge/miss/buck, what ever you want to call it did not go away.

Ok here is where I am at right now. Last night I cleaned the Maf and my cold start issue went away. The car did not miss that bad on the way home yesterday when it was 78* outside but this morning...

I have people telling me that my miss is caused by airflow into my cold air intake???? I did install a small plate trans cooler in the bottom opening of my front bumper. The cooler takes up about...

Sorry I did not download the current tune. It was very late when I got home and I had to take the airboat with me to work today because I am leaving for the coast.

What did you see in the MAF...

The shop worked on the car all day yesterday and they are telling me they think it might be an injector. They want me to send all the injectors off to be tested. The injectors are only a year old and...

I use Hp Tuner on my C6 corvette but I have never messed with it on my truck. When I purchased the truck I tuned it with a PPE tuner. Would I be better off using my Hp tuner to tune the truck?

Love the Clutch! We just received the first tripple disc for the ZL1 Camaro. The factory clutch lasted 6 passes before it went up in smoke. They have sent out one other clutch to some guys in FL but...

Last night I went through the wiring with a meter and checked everything. I also made the suggested tune corrections but the lean spike was still there. It was not as bad but it was 40* this morning...

Like this? Is this what is causing the lean spike/miss?

anyone have any ideas?

I have a 2008 C6 Corvette W/auto. 416CI ls3, 3800rpm stall, 102 intake, full exhaust, injectors, etc.

The car has a len spike at cruise and I just cant find what is causing it. I have checked all...

I want to change the settings on my stall converter to lock at the speeds listed below and unlock at 30% power. What do I need to adjust in HP tuner to do this. Right now my stall only locks up in...

We will start adjusting the tune tonight.

We have also started a ZL1 build and the only thing holding the build up is the Tune.

Blacker we are doing heads, cam, exhaust, pulley, CAI, intercooler, etc.

I am good with turning off TM but will it hurt anything? The trans guys is the one who turned on all of the TM settings. I know you run your stuff at 100% like I do so I trust your advise. As soon...

We have been working on the car for a while now. Last year I blew the stock motor up and replaced it with a stroker motor, I also had the trans built, and changed to a ZO6 rear diff. The tune is...

I have the book and I have the CDs on the way. I was just looking for opions on the tune and what areas I should look at.

I am new to HP tuner but I am learning. Several people have been working with me on my tune but I would like to get some other opions on my current tune. My shifts are at the correct RPMs but they...
