“My experience with Larry from Powerhouse has been a very good and positive
one. They have always been fair and honest in all our dealings together. He has even driven to my place many times to install parts for my Viper. I
would recommend Powerhouse to anyone needing a competent and honest

“ have been using Larry at powerhouse performance since 2008 when I
purchased a 2008 srt-8 challenger started with 425hp built and tuned
to 845hp have had to many since then to talk about but the most recent
one is my 2015 challenger hellcat started with 707hp upgraded and
tuned to 965hp still have these two and they run with no problems to
this day so from GM FORD or the best of all MOPAR Powerhouse
Performance can build and tune them all to what ever you want!!! Would
not trust anyone else with my Tuning Building or Upgrades of any type
to anyone else!!! The MAN knows what he is doing!! Hard to find these
days!! So from sales to service to installs to tuning he does it
all!!! Carl Pence satisfied client!!!”

I have now dealt with Power house HP tunes for more than 2 years now
and I couldn't be happier.

They offer first class service. It's very clear that the customer
comes first. Even though I'm located
overseas in Sweden I have had full attention and assistance required
to tune my very special engine -Viper GTS-R

Due to the above mentioned I feel I have become more than a regular
customer, the customer and store relationship has over time developed
in to a true friendship where I even have recently visited the shop in
question on my trip to USA!

I would recommend this shop to anybody without a blink. Top notch altogether.

Thank you very much for your service!”

Larry helped me get the parts for my 2014 Challenger.
As far as the service he also installed the parts in a great time frame.
He also tuned my car to get the most HP I could get.
All of his work was without fail and when I drove the car, it was Great!

His prices were very reasonable and his work meticulous.
I would recommend him to anyone.

I have owned 2 excellent Vipers from Larry's shop. I usually finish events on the Podium. His service and work was exemplary. I wish the other modified Vipers I owned had the same quality of help.
