The Boost Creep Ltd is Northern Colorado's foremost dyno tuning facility, and the home of Harvey Epstein, one of Colorado's most experienced tuners. Scroll down to read some testimonials from previous customers.

I offer extensive experience in building, advising, troubleshooting, and calibrating engines and control systems. Originally, my area of expertise was with the muscle cars in my hometown of Tulsa OK, but computer controlled engine management and supercharging have become my new specialties. I am well known for any make or model performance calibrations. TheBoostCreepI love to tune, regardless of brand or output level. It is a passion I have had since watching drag racing on television in the seventies. Every engine, including yours, is very important to me. Thousands of engines have been calibrated by me and I enjoy the process now as much as I did as a go-kart tuning ten year old.

I know how to tune many different standalone systems including Autronic, MoTeC, Hydra, Link, Vi-Pec, etc. I am licensed and competent with reflashing utilities such as Cobb AccessTuner Pro, Diablosport CMR Custom Mapping, and can also handle systems like the Predator or EFI Live. I also know many different engines and have experience with calibrating 1 to 12 cylinder engines. I am happy to work with new interface and systems as I understand the basics behind all of them. Most are MAP or MAF sensor based and the underlying principles are always the same.

I have been dyno tuning cars full time for more than eight years. I have been as busy as 3 cars per day at times. With the setup of this shop, I am offering better tuning services than previously possible. The layout of the dyno is perfected. The makeup airflow is tuneable and overbuilt. I am located off I-25 in an industrial zone near a steep uphill with a 75 mph limit and multiple entrance and exit ramps for low speed testing. I can make all sorts of noise all the time. The setup I have laid out allows for truly efficient use of dyno time. Airflow is amazing, setup is shorter than ever, and I am running the show.

I am available by appointment only, but feel free to drop in Monday thru Friday, and some Saturday or Sundays too. The business line is 303-219-6071 and we are located at 245 3rd Avenue, Longmont CO. Click here for directions.
There is an E85 ethanol station open a few blocks away from the shop. This is my favorite fuel, so this location makes it convenient for customers who need to fill up after their tune.
