2015 Silverado with a stage 2 TSP came in and made some solid gains. We picked up just under 30 rwhp over the mail order tune it had and fixed some drivability issues while we were in there!

We have two BTR LT intakes for sale discounted. One is a truck intake. Discount is larger, we ran it on the shop truck. On the fbo 6.2L, it gained about 38 hp up top no cam. Larger gains with a camshaft.
We also have a mid length Trinity intake. Only used for dyno time, basically brand new. This intake will fit under the hood of a sixth Gen camaro and is designed for upper RPM performance.
Message for pricing in either one.

At Greg's Tuning Operation, we love to help our community. Today, as part of our community betterment outreach, we are offering a new special to help make the roads safer and less appalling. If your truck or SUV is squated, we will offer a 20% discount to get it level. This is good for lowering the truck or lifting the truck, as long as Batman is no longer triggered when your head lights come on.
