That's the correct B&G
no they aren't cheap by any means
However, the stock electronics has torque management configurations that prevent the engine outputting numbers over certain stock limits, so flatten the curve as you may, which increases seat of the pants, and power through the curve, but with the stock comps, you simply won't go over the peak allowed before it rains on your party
i typically only suggest it to people who actually are dead serious about lifting numbers
without them, if you simply look at the peak figure on the dyno, what twack said about no benefit is true
however if you overlay the stock curve with the modified curve, bolt on's it will lift and flatten it, the crash at 4k didn't go away until the TB, i had originally thought it to be an ignition/spark/fuel issue until we dynoed a 04 kj that was in the parking lot bone stock and it had the same 30hp drop at immediately after 4k
once the stock management numbers are reconfigured it's a different ball game, but i did throw on a stock TB and redyno it awhile back out of wasteful curiosity to see if it would dip at 4k again, and it did
and I hate when I get curious like that because it takes a few days and a few hundred miles for it to run correctly after a swap and before a dyno, and another few days and a few hundred after swapping back
I actually need to get it back to programmer and up the idle 50 rpm it's knocked off on me a time or two since it's warmed up
but the way I look at it, you are by no means limited to about 75hp at 2k rpm by any means
