With only 7200 miles – this ’04 Cobra ran like a dream. But the owner wanted the power up even more so with Kenne Bell blower that was put on, we also added fuel pump upgrades as well as performed custom tuning to make it scream.
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.
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.
A perfect starter package for your modern daily driver or pride and joy; a cold air intake and tuner are a great pair that delivers performance you can feel and a sound you will love. Factory intakes have several pathways and air restrictors inside of them to slow down and in some cases block airflow for a quiet, almost no-noise intake sound.
While that may be preferred for some, the rest of us like hearing our V-8s breathe. Call today to get your quote on a tuner and CAI package today!
Really nicely built/restored willies with a late model 5.3 swap showed up for some trans tuning. The factory calibrations for these transmissions like to hold off on a downshift alot longer then you really want sometimes, also the shift firmness properties and upshift at wot scheduals really need a little work to make feel right. A little time with HP tuners and we are much happier with how the trans operates. Also this swap used an on off electric fan arangement where the factory fan was a pulse width modulated assembly. So anytime the fan was commended the poor 30 amp relay got a seriouse HZ workout. By modifying the PWM tables to command 100%duty cycle when we wanted the fan on got that problem taken care of and allowed the realy to operate properly.
Super nice truck
