Hey guy I just bought a truck with ported votech heads, cam, 10:5:1 comp, jegs vortech intake, headers and full exhaust, tb spacer. The previous owner said he ran out of money to buy the tb so I wanted to know is the gain noticeable over the stock tb also it is tuned so I know I will need a retune just checking befor I drop 500 on a tb. Thanks Will

 

consider doing a datalog to determine if you MAP readings are less than 90 at load WOT. that would indicate a restriction in intake flow. 100 MAP is atmospheric pressure and zero vac.
