Get stock TB ported or go to 80mm or 85mm TB? or LS6 intake?
05 rcsb 5 speed 4.8l.
Already have every bolt tune, underdrive, headers, no cats, gears, CAI, etc besides cam, heads, blower .
Should I get my current TB ported and polished for 50.00 or just go to an ls6 intake or a fast or BBK intake and an 80mm or 85mm bbk or fast throttle body? I know its more of a WOT increase, kills bottom end.
Thoughts? Im sure its been talked about before.

Why spend the money on a smaller motor? Because soon hes gonna tap out the very last bit of power from the 4.8 and have wasted all that money only to wanna put a bigger motor in...If i could do it over again id have dropped a 6.0 in my silverado before modding my 5.3, but wasted all my money on the small motor and want more power now

Its a regency rst pretty rare in the silverbitch color so I dont want to hack into it too bad.. So far anything I have done is reversible and kept anything taken off.
I was going to have the throttle body ported/polished but than saw to add the ls6 intake for some extra ponies. Then i saw the bbk and other molded intakes with 85mm throttle bodies for even more ponies. Which setup works the best, I know the bbk and fast will outflow the ls6, not too worried about heatsoak on the aluminum ones.
So in the end I wont spray it, if anything it would be a maggie on top or a passengers side turbo.
For now that is on hold until my house is done renovations in 2 years or so.
So looking for bolt on's to rip around this summer.

Why are people so scared of spray? You get the same power as a blower for 1/10th the cost and if you don't go cheap on the safty wquipment its just as safe or safer then boost....
