We had Jesse Chaligoj in last week with his Fairmont with a stock bottom end 4.8. We had to chase a few issues like a map sensor leaking boost out of it but got them fixed. We ended up making 909 hp. This car is gonna be fun to rip on.

We had a Mercury Cougar in with small block Ford. We picked up decent power tuning the sniper but, he was going back and forth on electric fan vs the flex fan he had on the car. I was trying to push towards the electric fan so we took the flex fan off and we got a decent surprise of 20 to 28 hp gain depending where we was in the power curve. A gain of over 10 percent. This is one of many things we tested. It's not always about finding big power, its about finding the hidden power from tune to fan or alternator or something else. Its problem solving the intake that only leaks under high boost or that the converter you bought off marketplace could be completely wrong for your setup. The dyno is great for finding power and solving issues and the problems that are hard to find.

The Aces EFI system installed in this vehicle is producing inconsistent results. Four consecutive dyno pulls yielded significantly different horsepower readings, with no modifications made between runs. Additionally, the idle counts varied substantially. Despite my efforts to contact technical support, including extended hold times and unresponsive live chat, the issue remains unresolved. In my experience, alternative EFI systems like Holley, FuelTech, Motech, Link ECU,Haltech, Emtron and factory ecu tuned by hp tuners have proven to be more reliable and consistent, and I strongly recommend considering these options. If you call or message us and a few other tuners I know in the area we are all going to tell you no, we won't tune your aces efi. We dont want put out a bad tune due to an inconsistent ecu.

We had Neal Nissen in today with 5.9 powered Cummins truck. He had set a goal of a horsepower number to get today with his diesel truck and boy did he not disappoint. The turbo and the nitrous and diesel fuel were all working in harmony as he blasted his way to his goal with the ac on. Watch your self when you out and a blue ram pulls up dont get caught sleeping!

We have been seeing more and more coyote powered cars. This mustang was very well put together and made right at 600 on 6 lbs. Once they get the suspension dialed in and some passes there gonna come turn this bad boy up and have some fun. We can't wait for them to come back!

We had a 2025 C8 Corvette in for a little extra bump in power with some nitrous. The kit turned out awesome. The nitrous express kit delived exactly what it advertised and made it alot more fun to drive. Stay tuned as this car is scheduled to come back for some more upgrades soon.

We frequently receive inquiries regarding our capability to perform Holley EFI installations. The answer is affirmative, we do provide such services. Additionally, we tune these systems on our Mainline Prohub dyno and troubleshoot any issues that may arise. Our primary focus is on Holley products. Currently, we have ten projects in our shop, all of which feature Holley EFI systems or are in the process of having them installed. Holley sniper, sniper 2, terminator x, terminator x max, hp, or dominator we can get you fixed up.

Worked over some issues on Richard Maheu’s Mustang today on the dyno. Car has been having intermittent overboost conditions that were hard to replicate. After inspecting all the mechanical pieces and numerous tests we ended up finding a dome sensor that was failing randomly. Got it switched out, also found another co2 leak and she’s ready to make some passes! Horsepower Proving Grounds
