How to Tune Your Pontiac Grand Prix GXP (DiabloSport Trinity T-1000) 

If youre going to spend 500$ on tuning hardware, get HPTuners and tune your vehicle properly...

Damn, you're car is hella nice, love the sound that exhaust system and those rims. I wish I had the GXP trim. Mine is only a 2007 Pontiac Grand Prix base, still has the basic steel wheels and all but I plan to upgrade those eventually. It was a rare facebook marketplace find, I got it last November with only 48,000 miles on it, has almost 54,000 miles on it now unfortunately due to doing some door dashing because of my financial situation. But I wont be doing that too much longer, dont wanna rack up a lot of miles on the car doing that.

I have the same tuner, but I installed a tune from overkill. You’re better off with HPtuners. You get credits for 4 vehicles vs 1 and the hptuners allows you to reprogram many parameters that this one doesn’t. All for the same price.

My 06 gxp grand prix oil burning is a pain in ass I had the range afm diasbler but it was garbage

I wonder how many transmissions his tune has destroyed so far

Nice car, Chief...did a quick double-take when I saw the video title and thought for a second it was a video showing how to make a GXP run like an old Pontiac T-1000 (i.e., rebadged Chevette) from the early '80s...which I couldn't imagine being in very high demand... 🤪

dude the more i see your vids the more im being swayed away from a charger an G8Gt

How much more performance (horsepower) gain do you even get out of this? Is it even worth $500? I have a 2007 GXP and I NEED to know lol

Nice car man !..you should get some more tubing and run your intake into the fenderwell and get real cold air

Hey on your cam position sensor was replaced what did your car do cause I have an 04 as well and it trying to figure out what's wrong with it its true over but want start up and I did everything under the sun

Super new to the car culture , I have an 04 Pontiac Grand Prix GT what should I do to get better performance? I've considered getting an upgraded transmission... Thanks in advance.

What's the benefits of tuning your vehicle?

Do you gain horsepower?

I like this car I just feel like itd be a nightmare to work on.

Nice car. I have the same. Where did I get ur cold air intake and what kind is it?

Does the the tuner already have tunes loaded on there for your car because I need one for my 07 gxp

Great video. Does it allow you to delete the rev limiter and speed limiter? 🤔

What kind of mpg highway do you get with dod turned off?

does your cooling fan come on with this tune ?

Will it work on my 2005 Grand am gt?

Would this work for a 04 gtp comp g

Idk if you still respond to these but. I plan on getting one of these but wanna turn off dod or the afm. Does this thing do that?

So how much hp did you gain for 500 dollars?

Any way to make adjustments for E-85?

This isn't "how to tune" this is how to apply a canned tune which is garbage.

Galaxy Silver Gang

What's 0-60 for this car?

What year is your grand prix gxp ?

I thought a tune would be wayyy more complicated. Good to know it’s not

Dude stay away from the trinity. Bricked two of my PCMs and cost me thousands of dolalrs in repairs and tow bills. 06 GP GXP, get EFILive or HPT.

Yoo!! You did all that to gain 4 horsepower 😂😂 you should have just mail-order tune or again get a Dino tune you would have got maximum power out of your PCM or ECM 15 to 20 horsepower with some upgrades 🤦🏾‍♂️🤷🏾‍♂️ especially if you're going to spend $500

mn cool

Throw it in the trash. Thats how you tune it with trinity
