Bought MAC LT’s & Pro Chamber today

[Nervouswreck]

I scored a brand new set of MAC LT’s today and matching Pro Chamber for $600 for my Cobra. I’m just curious what i can expect for gains . I’m running a Posi Port ️, 2.76 upper only, 60 lb injectors , BAP, etc . It’s a wimp compared to what most of you guys have . Currently I’m 520 hp/ 515 tq. Just curious what the consensus is on gains. Thank you !

Gain some noise.

Maybe a faster response to pedal

And maybe a drop in boost

I suggest using the oem steel header gasket
