So I see a lot of stuff about upgrading the stock TB and MAF unit. With stock head and intake does this yield a hp increase? It seems that the companies advertise it as such but they don't really say if the unit they have tested is stock or modified. I could see the increase happening on a modified engine but not really a stocker. Straighten me out guys/gals...Thanks.

 

The numbers that you get when upgradeing MAF and TB with stock heads and intake are very limited...Heads and Intake really allow them to open up there use...i would imagine you'd get maybe a few hp out of upgradeing MAF & TB...nothing special untill head & intake work is done tho

 

C&L has dyno proof of up to 16 HP increase with there MAF kit on a stock car

 

Thanks, I'll check out C&L's website in more detail.
