Yep the graph is photochopped

Like i said i did 3 stock pulls and TQ was within 1 each pull. The next all my final pulls TQ wise were 470-480 area.

Sorry for posting results next time I'll just keep them to myself and my customers.

Nobody said that it's Photoshop'd.

The reading/calibration just simply cannot be accurate. You didn't gain 75lb/ft of torque from what you did. It hasn't happened in any other C7 that has been tuned with these mods, nor has any car in history made that kind of gain with these types of mods and tuning. It just doesn't happen and the reading is incorrect, plain and simple.

OP Thanks for posting your numbers.

There are no secrets for a header and tune application. It is always an average horsepower/torque gain. You can not push the numbers and then expect everyone to accept it. Nice try, Sir.

People have consistently been getting about 25whp and 35rwtq. That's what can be expected.

Push?

I guess I'm just posting some inflated numbers. If all tunes and bolt ons were the same why doesn't every car perform the same?

You have made your point and seemed to be a honest about your product. I am not here to bash.....just wanted some reality.

Just found this post where one made really close to the same tq stock as the one i did.

Agree torque gain seems astronomical for just headers and tune. Mine gained 34.5 hp and 41.3 ft lbs on ARH mid lengths and tune.

Awesome information C7 GrandSport. This is a very nice find for me because the Mid-lengths have been discussed in another thread as being a waste.

I have no problem with your stock numbers, sir. Just the headers/tune results. Anyway, what we see on paper it what we have to accept. Good numbers for you.
