We received a call from a customer who had just installed a newly built big block engine in their hot rod; but experienced constant backfiring and the car just wouldn’t rev. Inspection found that several timing related components were far off from where they should have been; resulting in a significant loss of power. Set everything up properly and the car now does 400 horsepower dyno pulls all day.
Updated: Blower is installed, belt is routed, and throttle body with the intake is on. Working on intercooler plumbing and some other odds and ends then it will go across the shop to the dyno to get some serious power out of it.
We have this ’07 Mustang here for a supercharger install and when its completed it will need to be fully retuned. The supercharger looks right at home under there. Check out the series of pictures showing the progress. Will post the final results on our Facebook page when its all done.
Update: The Mustang is just about all buttoned up and ready to go on the dyno for the tuning portion of its visit.

Today number 308 is here for a dyno run and tune to find the proper air fuel mixtures from idle to redline for power at any point in the race while being within the guidelines. Check out the pop-off Sparco steering wheel and the required cage.
Another local shop brought us this Jeep project after doing a beautiful job putting it together to be tuned and get the engine broke in and sorted out. A fast EFI setup was used and worked great. A single plain manifold modified for port injection was used for induction.
The engine ran pretty rough with the start up file it came in with so we spent some time on the dyno sorting it out. End result was 400rwhp through the th400 and throwing the big tires around. LS power is awesome.
After having a Stage 3 cam from Comp Cams installed; the factory MDS was causing loss of power and performance. We created a tune file for the vehicle disabling the MDS and were able to tune the Hemi to make power to an impressive 6390 rpm as opposed to the 5200 rpm limit when we first got it.
After making a strong 403 horsepower run on the dyno; the customer was happy with the results and the car is going to be turning heads with its new lumpy idle and howl from the Corsa exhaust out the back. Under the hood shows the custom painted engine cover in classic Hemi orange.
