New edge Mustang GT with a Kenne Bell supercharger came in for tuning adjustments. Made 476rwhp & 517rwtq, healthy numbers for a 2v.

The owner is listing it for sale, asking $15k. This car is pretty damn clean, and practically a budget terminator. Owner is tagged in the comments, contact him if interested.

Congratulations to Brian Adee on winning his class at Weekend Warrior Race & Relax. This event is a short Drag & Drive style event in western Colorado.

If the stock differential survives, this thing will easily run into the 8s at full weight - 4k lbs+ 👀

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 👀.
