Another blazing hot day on the dyno. Today we had a 99 Pontiac Firehawk with a LS3 swap on the rollers. Had the usual bolt ons, stage 3 cam, 93 octane fuel, LS7 MAF conversion, T56 transmission, and 3.73 rear gear ratio. We ended up making 497hp and 502 ft lbs of torque to the wheels.

We got this supercharged 6th gen all finished up this afternoon. 2016 6.2/A8 car with a baby Vortech supercharger kit, along with a full LT4 fuel system and E85. This car still has the factory camshaft, factory mufflers, stock intake manifold and throttle body. We got the fuel blended to around 65% ethanol content and we ended up at 572hp and 584ft lbs of torque. Not too bad for the 90+ ambient air temperatures. Car was pulling 3+ degrees of timing due to high IATs as well.

Just wrapped up an incredible 5-day deep dive into GM ECM controls and calibration strategies, specifically in HP Tuners. I want to extend a huge thank you to Calibrated Success for putting together such an outstanding learning experience!

The opportunity to learn directly from one of the most knowledgeable and respected calibrators in the industry was invaluable. His willingness to share real-world knowledge, advanced techniques, and years of experience is something I truly appreciate.

The automotive calibration industry is constantly evolving, and staying committed to learning is what separates good calibrators from great ones. Every opportunity to expand my knowledge is an investment in my future, my customers, and my craft. We are truly committed here to giving you the absolute best level of calibrations, customer service, and the after care once your car leaves the shop.

I'm excited to apply what I've learned and continue growing as a calibrator. Thanks again to everyone who made this experience possible! We truly appreciate every single person who has walked through our doors as a customer, vendor, or any shop and individual who has done business with us repeatedly! We wouldn't be where we're at now without every single one of you! I will forever be grateful for you all!

A special thank you these specific business and individuals who've really helped put us on the map and grow to the level we are at! I can't thank you all enough for allowing me to be a part of your projects!

InjectorExperts Keith Brewer for constantly giving us opportunities and treating us like family for the last decade we've been working together. This is the guy you need to see if you need injectors serviced, or need data collection for your set of injectors!

Chris Smith with Custom Automotive. Chris has been a key factor in our business from playing multiple rolls as a vendor to a customer, and a great friend alike. If you're looking for a shop to get your project going from start to finish with the highest level of details in paint, workmanship, and quality parts, check them out!

Franky Weldon at Weldon Racing for being a great customer, partner shop, and more importantly a true friend. I tell everyone that this is THE guy who rooted my position in the industry in our local area. We've learned so much working with one another that I can directly measure my success having developed the working relationship that we have! If you're in the Bowling Green area and need work done on your vehicle, they will get you straightened out!

Again, THANK YOU to every single person who has been a part of this journey!

Shops been busy busy last couple weeks. Everyone whos waiting on us we are doing our best to keep things moving, so please be patient. We got the Hemi in Johns Durango R/T buttoned up with a Btr truck norris cam and some Stainless Works music pipes, now shes waiting for some up arrow keyboard action from the boss. Up next is Davids beautiful ls7 Vette on the rack for a complete front to back make over with all the goodies so its brand new again. Also buttoning up Brads turbo Silverado as he has a few leaks to take care of and then its in line for a retune to squeeze some more power out of the 5.3.
