Well to make a long story short. My brother has a bolt on GSR. Full exhaust, intake mani, tb and intake. He took it to get tuned today behind my back to a shop I dont trust and came home with a dyno sheet reading 195WHP 141 TQ. I told him his tune has to be lean to the max. My built GSR makes those numbers with pistons, cams ect. However he will not listen to me. Can anyone verify that a stock bolt on GSR safely making these numbers? I cant rap my head around this, and can not for the life of me explain how unsafe this is for his motor. Anybody have a good write up that would explain something like this to a person who has limited knowledge about cars?

P.s. I will post his dyno sheet when he gets home.

I don't even see how a generous dyno could give those numbers running stock cams and pistons...

Dyno numbers mean nothing. They very so much depending on a shit load of conditions. If you go on a warm day, you will get one set of numbers, then you can go on a cold day and get a completely difference set. It would be more impressive (or even worth making a thread about) if you posted numbers from your pull with a completely stock car, then do the upgrades and do a pull on the same dyno in roughly the same conditions.

There are people that build cars just to put out good numbers on a dyno. There are actually competitions for it. So, if you're one of those people, more power to you. If you are actually trying to build a car that is functional, and you want to use dyno results as some way of tracking your progress, then you should dyno it a lot more and check for improvements.

...also adjust the weight distribution for best results.

You can adjust correction factors on a dyno to make a car look like it's making more power, or less power, than it actually is.
