what is the size of the TGP's throttle body?
Save getting an expensive upgrade, the intake and heads would need to have more air flow to have any benefits from a TB upgrade!! I have seen long and detailed statements made with formulas and proof that it is the entire air flow calc that needs to be run to determine when some upgrades are warranted/beneficial, and for now those gains stated by larger TB are with mod?d engines that could use the extra air mass of a larger throttle body, but they do not mention if the computer chips can deal with the flow dynamic changes in the air flow, such as for AE fueling and timing.
