Mp112 any gains 75mm to 90mm TB? I've got a beater 5.3 Malibu swap car that I'm putting a MP112 on (truck style) the car is currently an 03 DBW setup w/75mm TB 8 pin. I have a 90mm J-tube and gold blade 90mm throttle body, but it's my understanding this cannot be tuned to achieve wide open throttle without the $250 X-link. Is there much to be gained switching to the 90mm? I have seached for 3 hours this morning and haven't found back to back dyno tests on the switch.
This is a sloppy mechanics style build, I know the limitations of the Maggie but I already had it and I'm curious. We've been spraying a 275 wet shot on the 5.3 for a while now with good success. Only mods are late Z06 cam/springs/moly pushrods. Planning on spraying at least 175 on top of the Maggie and maybe Meth too. This is a see how quick the car can be before it blows project.
