Ported LS1 4.8 5.3 TB
I bought this last year but only used it for 2 months before swapping back my stock TB because the cruise control fitting was a different size. I forget who did the porting but it has the slightly larger than stock throttle blade. You need to swap your IAC and TPS. $50 for the TB with your core in exchange or $75 outright.
