With driver mod, maybe high 13's??

But I would not use a TB spacers or MSD coils, they are worthless mods. MSD coils are known to fail.

Since you have a Throttle Body Spacer, I'll say 11.01

 

[Pontiac Grand Prix GT]

What coils should I get?

What coils should I get?

Stock.

 

[Pontiac Grand Prix GT]

Good thing I Kept the stock just in case.what size pulley could I drop with the mods I got.

Best question is how you are going to tune this thing?

 

[Pontiac Grand Prix GT]

My friends owns a tuner shop.

Do not drop further than a 3.6

Do you have some kind of scan gauge such as an Aeroforce? If not, you need this. You need to monitor KR.

This.

In-car tunes are the best.

 

[Fivefingerdeathpunch]

Incase you didnt know, your 2007 car is not tune-able. You will need a 04-05 pcm to make it work, and the gas gauge will read backwards. Do some reading on that.

 

[Pontiac Grand Prix GT]

I need to get an AuroForce. With the 3.6 how much KR do I have in any.

Aeroforce*

You have KR, I am positive.

Hopefully no more than 2-3*

 

[Pontiac Grand Prix GT]

Idk much about KR how bad is that

 

[DanPrixGTP]

Google.

Use it.

You need to research more, much more.

Ps the only "mods" you've done that MIGHT yield any type of pick up in a 1/4 mile is the pulley drop and headers. Yet without a tune the mods are useless. So whatever a stock 07 GP GT runs, that is what you'll run.

id throw a little race gas in it if you do go to the track, on a decent tire it would definatly go high 13's, my 06 had a 3" catless down pipe k&n drop in 3.4 and race gas and went 14.2 but had no traction in first, a set of dr's and it would have been a solid 13.8-13.9 car

 

[Pontiac Grand Prix GT]

Thanks everyone. I'll deff. run race gas.

Race gas won't help for **** if you're knocking. Get a proper tune before you even think of running the car hard.

Yesterday I was scanning and had anywhere from .5*-2.7* KR on my 3.4. Same results when I later switched to my 3.5. Put some 100 Oct in, no KR...

 

[Pontiac Grand Prix GT]

Where I live we only have 93 octane, and I buy octane booster as well
