Novi 2200R C6

Put Brian's 05 Novi 2200R equipped vette back on the dyno to see how it was doing before we turn it up. Made a solid 821 in 105 degree heat. Back in November it made 808. Stock bottom end has held together well. How far can we push it?🤔 #Sendit

Twin turbo 2nd gen Viper is ready for the dyno. We will be aiming for 14psi. This was a few little 6.5psi pulls to check controller.. It's on an AEM V1 stand alone. Sorry for the wind.

2.9 Whipple El Camino

Beautiful El Camino pushing 718hp SAE 749 STD. Tq readings weren't working for us today but this thing has to be 800+ the way it hits. 2.9 Whipple powered 427 with RPM 4L80E on 93/meth. Car is also on a Holley Dominator ECU.

2014 1LE Camaro

2014 1LE with TSP cam and speed engineer headers making 463/421 SAE 483/438 STD. K&N intake seems to be a restriction and look forward to getting a better intake on it.

2013 ZL1 A6 543hp/542tq

2013 ZL1 A6 Hennessey "700" package on 91 octane came in making 522rwhp SAE and left making 543rwhp SAE. Gained 21 peak and about 10-15 across the band on previous tune. This is a stock manifold/exhaust car and has a third muffler added for noise and we feel it is hurting the power.

2012 ZL1 with Texas Speed & Performance LT headers and Roto-Fab, LLC CAI put down 495/489 SAE and 510/504 STD. Injector duty cycle was at 90+% up top so looks like some injectors along with some other go fast parts will be coming next.

Creep test

Testing out the creep setup with the Maxxecu / Maxxtuning AB. Stay tuned for a rolling antilag video next. Changes since the last setup are the 76mm Underpressure Power & Performance from their 67s which performed great. Also added a new armed air setup for waste gate control. Everything is controlled by the MaxxECU.

Took a little time for myself today and got the new Underpressure Power & Performance 76s mounted up. These are their biggest billet wheel turbos and I'm excited to see what they can do. Don't forget they now offer Garret turbos with their kits now as well! PM us for ordering questions.

2011 Callaway Camaro

2011 Callaway Camaro all buttoned up and ready to hurt some feelings. This car runs like a stock car on E85. No cold start issues no bucking it's truly like it came off the showroom floor. Stock tuned numbers on another Dyno were 489/504 STD.

2011 Callaway Camaro. Swapped out the 1 bar MAP for ZR1 3 bar and some Injector Dynamics 1050X to compliment the DSX Tuning flex fuel kit and external pump. Ran into some heavy belt slip from 5500-7k. Made 595/[email protected] on E85 then fell flat to 4.5. Hopefully the 3.4 Griptec pulley will give us the boost we need!

Working on the on board air install for the Jekyll & Hyde Performance twin turbo C6. This will be controlled using our Maxxecu / Maxxtuning AB stand alone ECU. Can't wait to see what this can do with our new Underpressure Power & Performance 76mm turbos. Freshened up motor from Late Model Engines and coupled with the RPM Transmissions TH400/9 inch setup. Last season we lost a close race due to running out spring pressure so this will help us a ton.

Here is a nice 40 degree cold start of the 2018 Silverado we just finished up. Texas Speed & Performance LT headers with full CORSA Performance exhaust.
