Default Boomba DBC Throttle Body Fitment?

I currently have a JDM EJ207 V7 engine with a JDM V8 Spec-C Long Runner ITMF. I just bought a Boomba DBC 75mm Throttle Body and I'm concerned about the Fitment. I did not realize the Boomba TB was going to be as thick as it is. I'm running a ETS.19x7x4 large intercooler core and I'm worried about the Fitment with the Boomba TB being a good amount thicker than the Stock Subaru TB. Does anyone have any personal experience with installing a boomba throttle body with a top mount intercooler? I just want to make sure I'm not going to have any problems with the TMIC hitting my front Strut Brace and or Firewall before installing and not being able to return it because of being installed. Any input, suggestions or help would be greatly appreciated.

Thanks Scott

if I could ask a question, why do you think you need a bigger tb?

I currently am running a aftermarket precision turbo, ported and polished heads, ITMF, with all supporting mods ECT.. My stock TB DBW mount broke, so Iím buying a lager DBW TB to replace and fix my problem.

Just need to know if anyone has ran the Boomba with A ETS TMIC?

- When you installed the 70MM TB did you retune the car for it after the install? Changing somthing like the diameter of the TB would for sure require a retune.

- Did you change anything else at the same time as the new 70MM TB was installed( ex. injectors, Intake, Fuel? ) that could play a humungous part of the idle inconsistency?

I was really just inquiring if anyone had installed a Boomba TB with a TMNIC and had any problems with the TMIC hitting the Firewall due to the larger overall hight of the TB?
