Finished up the homies jeep and tried out the chassis flex for him.
Just something about flexing jeeps gets my blood pumping!!

Thank god this one sports a BTR red hot cammed ls3 with Kooks longtube headers! So it don’t sound like some silly jeep 🤣

Attention in the pits!
I know this will p**s some people off but I will not be here next week.
We will not have phone, message, email, pigeon mail, usps mail, AOL, chirp, or any other form of communication.

I am taking a week off from work for the first time in 2 years and I don’t want to hear no p**sing and moaning about it!
Ms Northern Performance asks me for about
5 things a year and her family reunion is one of them.
I’m going to cruise my 69 Camaro around with her and have a wonderful week away from the stressors/pressure of my normal day to day.

The guys will be here with their scheduled work holding it down. Doors will be locked up and they too will just have an easy week in peace without me cracking any whips.

The 69 is badass btw!!!!

Kenny stopped by today to get his 1979 Malibu tuned up. 280 whp it’s ready to go bar to bar in a flash!
Found 3 bags of w**d inside from 3 different generations, 2 dry rotted condoms, and divorce papers from the 80’s.
Such nostalgia. If only this car could tell stories.

My brother in law Nathan with single source composites finished up his super sweet RAM.
You can never go wrong with a classic vehicle and modern drivetrain!
Quick once over with the Holley terminator x and she runs great!
If you guys need fiberglass or carbon fiber race car parts. Remember to shop with Single source composites

Your mind off from the big ones 🤣
Joel tackled this one today.
Mike’s Camaro back for a fast 92 setup. Almost 25rwhp gain over the oem intake.
The car is a factory cam and heads car. He wanted to do the bolt ons and get them all out of the way.
Fine 2001 unit here. Great color combo.

We have some sweet s**t coming up so stay tuned!!!
We are so thankful for all of the calls and messages. You guys are awesome!
You guys are making it hard to keep up! At this moment I am about 2 weeks behind on calls. Not quite a couple hundred to do but we are getting close. I will be on the Dyno the rest of the night. But I will be back on the office for the first half of the days all week! So have your phones handy if you are waiting!

Happy 4th from us truck guys over here! Hope you all have a safe and fun holiday weekend!

Wanted my boy David to be able to enjoy Merica day tomorrow.
So he brought his turbo TA up from Detroit area. This thing should rip pretty good.
Been tuning on this car since 2018 when it was n/a. Then nitrous. Now turbo.
Love ya dude! Have a great holiday weekend!

I haven’t posted enough about this car on our work page as I usually share on my personal page.
This is our first go around on a pro touring car here at the shop top to bottom!
454ci aluminum Ls. Ls7 heads. Rpm 4l60e. Custom dual 3@ exhaust. Front tubular subframe. 4 link swapped. Fuel system. Ac system. Hp tuners core ecu and harness. Even the interior was all done in house for the first time here.
I want to start doing 2 of these cars a year. All similar but very different and selling them. I can’t say this one is spoken for persay but it has struck a lot of interest.
For all of my labor I am going to be rewarded by driving it through my birthday the end of August for my wonderfully dreaded 40th birthday.
Then it will be available!

This thing turned out wonderful! This is sheer perfection. Classy classic interior. Over drive transmission and over 700 naturally aspirated flywheel horsepower on tap. Lightweight. Nimble. And for the sake of calling it how I see it.
One of the best looking cars to ever land tires on the pavement.

Have a happy 4th everyone! Be safe but make sure to celebrate the freedoms that we take for granted daily!

My buddy Kam brought a few rides up for tunes today. Knocked out this cammed 5th gen that he built for a customer of his. Tuned up his ole be**er work truck with a btr cam kit and retuned his cammed c6 after a trans issue that was resolved with a dealer engine/bcm return to stock.
One of them totally humbled me as well as another fellas Red 08 Vette a few days ago. Been a while since I was absolutely stumped with no answer or no one to turn too.
But between a few intelligent brains across the board and some luck with a patient retry. I was learned a couple things.
Kams c6 had an issue with the bcm/ecm locking the trans in 4th.
Another (the red one I referred to) had a fumbled up can/system ID in the tcm side locking the car in 4th. I read the car as per usual. It created its own id and p**sed the car right off. Upon returning to stock with a new OS it fixed itself. Two separate vehicles with two separate causes with the same issues.

Have I mentioned that I hate cars so much 🤣

Now I can have a peaceful 4th weekend not stressing over these things.
