Do headers and tune really gain close to 100rwhp? 100rwtq?
Is it possible to gain this much power with long tubes and a dyno tune? I'm assuming the deleted secondaries and deleted resonator is more so for the massive weight loss than actual power gains.
Also, do people normally run low 11s @122-125mph with these few mods alone?
Is the car pretty much maxed out after these without adding a blower or opening the motor?

Pre tune, Most non-P31/507 cars will dyno in at 360-370 rwhp stock.
Post tune, the car will be around 410-430 rwhp.
header/tune, cars are running in at 460-480 rwhp (some have run higher numbers).
That's how sellers are deriving that 100rwhp. Due to multiple variables, it's not an exact number, but more of an approximation.
There are a few more items that you can do to get more power, but it won't yield the gains that a header/tune combo will give you. With the exception to a few shots of nos.

Thanks guys.
Jeff-
Do you think a car with headers, dyno tune, deleted secondaries and deleted resonator is capable of low 11s @125+ or close to that? That would be my ultimate goal.

If you look on the sticky timeslip thread, it appears that with reputable long tubes, a good tune, high octane, and some sticky tires ... running deep into the 11 second range at those mph is attainable in the right hands.
