We actually were at a stopping point and ran out of injector. You will see, there was a bit more work to do in the mid range in regards to fueling. We will be installing an AEM EMS and 1000cc injectors and retuning shortly.





The only change between the two graphs below were the IAG Heads and Kelford Cams. No other changes!

^The mid-range is still being tweaked. I'd be willing to bet 420+tq will be realized after Jorge works his magic.

That seems like a really nice set-up. 460+whp and 300ft/lbs of torque before 4k rpm is badass. Nice fat power band

Car honestly feels great on the street. It keeps pulling and pulling..... Can't wait to put AEM EMS on it and retune. We are very happy with the results of just our heads and cams. Here are some picture while we were flow benching them.

This car is sick. if you saw this car on the road you would never think that kind of power is under the hood. IAG does awesome work.

If you consider front mounts on the interior, maybe.
