Here is an article from CarCraft that will explain the two and how they are different- http://www.carcraft.com/techarticles...ion/index.html

Fuel trims CAN be changed with a power programmer, but not by the end user. They would have been changed by the manufacturer for their specific tune. These trims will still not be accurate since you have an after market intake and they generally use stock trims on the power programmers. If you were to go the route of using us or finding someone locally with HP Tuners, both would be able to correct the trims for your specific application. The power programmers are a good start for someone with stock parts looking for more power, but once you start going with a custom setup its better to get a custom tune for your specific setup.

 

That CarCraft link was excellant.It brought me up to speed from when I was able to easily modify & tune cars myself [ back in the late sixties & seventies].BNRacing,I'm sold on your logic.It did however,say that MAF systems [ the category I assume my 2010 V-6 Camaro fits in ],are self-compensating for most reasonable upgrades.I gather your saying that you can further improve on that.Is it still okay to call you,Friday,late A.M. ? thanks,westmassk

 

I'll be available after 5pm eastern time. (I work a regular 9-5 and tune cars on the side)

 

Just got your message, I'll call you back after 5pm eastern if that's ok with you?
