Kicking the idea of expanding, with this dyno coming I'm hoping to be able to gear more towards tuning than mechanic work / swapping.

With that being said I can always use an extra set of hands as I can only get so much work done a day solo!

This isn't a guarantee but would like to discuss a possible hire with anyone interested.

Pm me if interested and let's talk!

Got some polishing to do on front runner / fuel rails, and pinstriping valve covers white to match outside, in final assembly on this k5 ls swap!

Finally talked this customer into ditching the FITECH and going with HOLLEY, he'll never turn back now!

Don't let anyone talk you into getting fitech or aces or any other cheap aftermarket junk! Go with quality!

Love a good k10!

5.3/th350 P59 pcm. Always a blast tuning these, however there's always a downfall to using the non electric transmissions with factory pcm. Without a speed sensor there are several tables you lose.

You lose the range sensor, (pcm doesn't know if in park or drive) this can allow the throttle to dip when going from park to drive.

You also lose a speed sensor unless installing an aftermarket one. Losing this can also make throttle dip when coming to a stop because you lose some of the seperate airflow tables (specifically green/blue DBW pcm)

Also a tight converter can make the throttle dip a lot more dramatic.

Recommended if wanting to use a mechanical transmission or older manual to use a p01 (Red/blue) if wanting to keep the factory style pcm.

HOLLEY IS ALWAYS BETTER 😂🤘🏻

80s Malibu rewire, final assembly and tune on the LT/6l90e swap coming soon! 👀

Got this nice 442 tuned and ready to go!

Previous shop had the shift points way out of wack. Your 4l60e/80e should not be shifting into overdrive at 15mph 😂

During the WOT tuning we found out the stock 25lb injectors were running out up top, swapped in the 50lb flex fuel injector for a broader range!
