bolton performance parts
i have added k&n filters, air intake system,borla stinger exhaust and x pipe and want to add the granatelli mass flow air sensors what i thought i read before is that none of this will do you any good (as far as horse power) unless you get it dyno and retuned. Is this true?
thank you

money and might cost you some power. Do a search on here about it and you'll see nothing but negative posts. Save that $300 and put it towards a good set of LT headers and after you get them then get the car tuned.

Couldnt have been put any better.
Ran great without a tune, and no issues. It would have run better with a tune. I know after the bolt ons, Id want more power, so I waited for the tune

This is a quote from "Dyno Proven GM LS1 - LS7 Performance Parts" p.18.
The LS1 test engine was a GMPP LS1 crate engine that was modified with a COMP XR265HR cam and LS6 manifold and K & N cone air filter.
Equipted with the factory MAF, the modified LS1 produced 462 hp and 440 ft-lbs torque. Replacing the stock MAF with a Granatelli piece resulted in an increase in power to 472 hp and 449 ft-lbs torque.
This is an increase of 10 hp and 9 ft-lbs torque.
The new MAF change improved the output from as low as 3000 rpm and carried the gain past 6000 rpm.
The Granatelli MAF also changed the airflow mixture slightly from 12.5:1 to nearly 13.0:1. The MAF showed impressive torque improvement even in the midrange rpm.
This changed my thinking. I try to keep an open mind.
Hope you enjoyed.

462 ? yep very very lucky

I'm expecting 430sh at crank
and 400 or close on the wheels.I'll let you know when I'm all done.

You ask "Who did the testing? GMS?" Do I detect a little sarcasm?
When statements are made, it is good to know if the statement is based on opinion or or solid fact. The information I shared is based on fact and I told the source, ie the book.
