Need your opinions on how many horses will be picked up with mods being done next week.....And an opinion on one thing......

Getting a Rotofab Big Gulp CAI, 180* thermostat, high temp spark plug wire insulators, custom Street/Dyno Ecu Calibration, and ZR1 throttle body...Rotofab themselves told me over the phone that if I dont upgrade the throttle body with the Big Gulp, I will leave HP on the table...Is that true?

I have an A10..... How many horse could be gained with and without the ZR1 throttle body?

Getting done at Tune Time in Lakewood NJ.....
