Very clean 2017 Sierra Denali with the 6.2 8l90. We did a Brian Tooley Racing stage 2 V2 cam and long tube headers on. Good power for not being in a 1:1 gear due to driveshaft speed limitations on 93 octane.

People always seem to want to over cam these trucks. Look at that tq and overall curve. IMO the best cam for these trucks for all around daily, towing and tq! This is why we don't over cam heavy trucks as we don't want to kill all the low end and mid range tq. Add a flex fuel sensor and you will see gains of 25-30 whp/30-40 wtq.

1970 Chevelle in with a built 6L LS with a FP turbo hanging off it. Holley X Max ecu to control the engine and 4l80 trans. This one is going to run really well on the street and strip when finished!

I havent post up much lately. So here's a clean 05 Dodge truck in today for a tune. Truck looked like it just rolled off the showroom floor inside and out.

I've got open spots for remote tuning this week. I keep my remote tunes to a certain amount as im not one to take days to get a revision from. And if you stack urself too much that's what happens. Imho that's bad customer service as who wants to wait days for a simple revison or take 1-2 months to get their vehicle tuned?? On most vehicles if the customer is willing to get me the logs I need I can knock it out same day.

2000 C5 in with a custom turbo kit built by Bad Company Racing LLC. 7275 precision turbo, 1000cc FIC injectors, 525lph fuel pump, RPM built trans and a BTR stage 2 turbo cam etc. Not sure on exact hp as we didnt have it on my chassis dyno today but we were at 96% injector duty cycle so stopped there. Good running street car!

Another DOD delete and cam swap getting finished up. This one is a 15 l86 6.2L with 8l90 trans getting a set of long tubes and a BTR 2 V2 truck grind cam. This is the perfect cam for big tq gains which you want in a heavy truck that still does well on the top end! Good idle chop, stock like drivabilty. Last one i dyno tested made 430s whp and 500 tq at the wheels on 22s and e60. Low 400s on 93 oct which is the setup on my personal 18 6.2 truck. We also performed a DI service while in there. Couple pics thrown in below of what the intake port and valves look like before and after a cleaning. Definitely worth having done on DI/Direct Injection engines!

We have done so many cam swaps/dod deletes and tunes this month it's been very hectic. Just wanted to stop and make a post and thank all of my loyal customers and new ones for putting trust in me to get your cars and trucks done right. I greatly appreciate each and everyone of you for the business and also the return business. Also would like to thank all my customers out there with the referrals as well. You're the real MVPs!

Flawless low mile 2016 C7 Z06 8 speed auto in with a set of headers, flex fuel kit, methanol injection and upper pulley. Fixed previous tune that was absolutely horrendous especially the trans tune! Now my guy can enjoy a nice driving reliable car!

2012 CTSV in for diag and repair work. Found a bad coolant sensor, replaced thermostat and retune. I suspect car has lower grade fuel as I couldn't get much advance in it. So put a nice soft safe tune in for him to run the fuel out and refill with good 93. Car is 100% stock. With fresh fuel easily will go over 500 and then some.
