Wrapped up a bitchin TRUE Street car, 5th gen twin turbo Camaro from Colorado came in for a 4l80e swap and tuning. Retained all factory functions, cruise control, trans temp gauge, PRNDL indicator in the dash and HUD.

Installed the Trans brake and bump buttons with a pair of S550 billet button mounts from Motion Raceworks, wired through the factory clock spring so there is no exterior cables to hang up or catch on.
Designed and 3d printed a console filler plate to clean up the void left from the oem shifter assembly.

Best part is kicking on the radio, converter locked up and AC blasting down the highway at 80mph with no issue. Full exhaust, oem mufflers.

Factory ECU & Flex Fuel - Started out at 755rwhp/703rwtq and finished off at 1165rwhp/972rwtq before running out of WG spring. Left more on the table for another time.

Long time customer decided it was time to turn up his combo, ran out of fuel pump, upgraded the fuel system and made a smidge more chooch. Keep an eye out for this unit at local street race events this summer 👀.

Haven’t shared anything in awhile, still cranking out customer work. I’ve been at capacity for awhile, just a reminder - tuning is 3-4wks out unless you’re an existing customer needing minimal tweaks. I am not taking on any builds until this fall. If you have something in mind, I’d suggest you get in touch soon so we can schedule it and make a game plan. Spots fill up quickly.

Now onto the cool stuff - Beautiful 1955 delivery that came in for tuning and diag. 525hp LS3/4l70 combo.

LS swapped Pontiac Solstice - Came in for a 4L60e swap. Bubba Ginn 60e/Converter combo. custom drive shaft from Tim Herr . 3D printed a filler plate for the console to clean up the old manual shifter location and added a line lock.

What are the odds this is the only Solstice sporting a Motion Raceworks Operator shifter? 😂
