Fueling Matters! – Updating a Camaro ZL1

We received a call from a client regarding an issue with a tune on his newly acquired ZL1 Camaro. The car was already  modified and sent on the way to the original owner with, lets just call it, a ‘rough’ tune. We can only assume this helped the original owner decide to part ways with the vehicle, and eventually brought Dynosty into the equation. We strapped the 4,000 mile car down to the rollers after evaluating the modifications listed on the original shops build sheet:

Pulley combination good for ~12psi, 1″ 7/8 longtube headers to a catback exhaust, cold air intake, aftermarket camshaft/valvetrain.

The thing that struck us; was the lack of any fueling to help keep this combination safe to romp around on the street. Stock ZL1 fuel pumps can see 650-700whp, ideally we like to see them upgraded as they tend to lose some pressure up top, but the stock injectors are another animal. At WOT we watched AFR climb to a scary 13.5:1 and decided to abort the run. How long exactly was the car being driven like this? We were unsure. We were positive that a call to our friends at Injector Dynamics would solve these issues.

In went a set of their proven ID850s and back on the rollers we went. After a few hours of fine tuning drivability and WOT, Hal finished the dyno session at an impressive 673Whp 652Tq. All on boost levels that could easily be increased with a simple pulley change, offering our client room to grow in the future! We love working with these LSX platforms, looking forward to an exciting spring!

Hyundai Genesis on Track after Haltech Tune and Upgrades

This white 2012 Hyundai Genesis coupe r-spec 2.0T came in for some mods to boost the power output of the 2.0L turbocharged Theta engine. Baseline dyno showed 178whp on our Dyno Dynamics, at which time we planned the following:
Haltech Hyundai Genesis Platinum Pro Plug-In standalone ems (PN HT055045)
Injector Dynamics ID 1000cc fuel injectors
MXP Downpipe
MXP O2 Housing
Tune by Hal at Dynosty

Next, the stock ECU was removed and a Haltech Pro Plug-In ecu was fitted in it’s place. Fuel, ignition, cam timing and boost were dialed in on the Haltech standalone, yielding 232whp on 93octane pump gas – a 54whp or 30% increase in power!

The customer runs the car at SCCA autocross events, and recently took it to Putnam Park road course for a Porsche track day event. He sent a link to the footage along with these kind words, “Here’s a video from the last session on Sunday. I was the only car out there on street tires in that session. The second car I passed is a 2011 GT3 on Hoosier R6’s. Thanks for the help and for the perfect tune.”
