Throttle Body
Throttle Body
I spoke with my Tuner and he is really aching to put a 65mm TB, per my existing mods and there is going to be a re tune as well what should I be looking at as far as numbers (whp/wtq), on the glorious cali 91. Would this be worth my time?
How much truth is there with the whistling from the TB when installed, kind of apprehensive since everything is running damn near perfect.

a 65mm tb offers great throttle response & as long as the inlet opening is increased to 65mm as well, my back to back dyno testing netted me an average of 5whp gain...some areas were more than 8whp up top!

the oem tb was run on a ported intake...so i dont know what a oem intake & oem tb will do against a 65mm tb & ported intake...
as far as the whistling goes, some tb's whistles while other dont, this is so with everyone who makes 65mm tb's...I recently discovered the cure to eliminate this whistle on 65mm tb's.
Based on your mod list, it would be a nice mod....especially if you favor transient response..the engine will feel more connected to your throttle input, around town, driving on the freeway & even when you floor it, the response is there
