Injected Ford 351 Oil Spreader F100 Edlebrock

New Ford 351 crate stroker engine, client brought this PU truck to us to sort out and tune the Edlebrock fuel injection system which was easy compared to fixing all the oil leaks. The cam plug, rear main, custom oil pan all were leaking. The installer did not lubricate the nose of the torque converter so the transmission was frozen to engine, very difficult to free. Truck tuned up nice and is also dry now.

ECU Computer GM Truck Tuning

We have been performance ECU tuning several Silverado, Suburban and Escalade trucks. Quite amazing improvements in power, economy and engine durability over factory tuning on both Vortec and LS engine trucks. 4.8 5.3 6.0 and 6.2 liter some we tune for 87 octane but the GM products respond best on 91 octane gas. The 6.0 / 6.2 GMC, Chevy and Cadillac trucks give quite a power / MPG increase with our tuning.

1934 Pontiac with 502 Big Block Chevy ECU Tune

This beautiful 34' Pontiac 502 big block Chevy engine had been tuned by two local companies and was still running 30% rich, it would fowl the spark plugs in under 30 miles. Hot Rods are a compromise due to layouts and require careful diagnostics with proper tuning. Our GM ECU tuning results are better response / power / mileage with less cylinder wear.

BMW Cracking Aluminum Bolts

BMW has started using aluminum bolts in various applications but especially in the valve covers. These bolts experience a heat cycle every time the engine is ran and this can take a toll on them. Even with a factory torque spec on them they still crack which allows engine oil to leak causing a mess and can sometimes even leak onto the exhaust manifold causing a nasty oil burning aroma. In this picture you can see the crack that propagates around the head of the bolt.

More GM Truck Computer Tuning!
Last month we had the privilege of tuning two Cadillac trucks. Both the owners, David and Don, are ecstatic with the results.

Carbon Fiber Wheels

These photos are of a true carbon fiber wheel. These one off wheels were made for WSU Engineering's SAE formula racing team by KU's formula team in exchange for wind tunnel time. Terry from Alloy Wheel Repair and I used Tracy's Tires latest equipment to change the first wheel. We then found my older equipment was actually a better combination. Time consuming, fragile and delicate. But only 3.5lbs per wheel!

Poor Mini Cooper

This Mini Cooper was purchased at auction not running, with problems unknown. The project was going well until we came to replacing ignition. Loose #3 plug has hard, baked on exhaust gasses. #3 boot is torn and distorted from the previous plug blow out, #2 boot has more old exhaust patina. This spark plug had been leaking for some time but still allowed car to run well until plugs were disturbed and the threads just won’t hold enough tension so the plug pops out. A Very disappointing find with this project. Research shows this is not an uncommon R50 and R53 Mini Cooper problem.

Tuning in this manner allows us to see true results with air resistance, shifting, and part throttle as well as WOT. Our tuning is emissions legal in all 50 states but gives more power, better response, and all factory sensors are kept active to create a better more efficient and safer tune. Love these cars!
