Don't take my word for it, check the thread I posted. The test car went from 80-100F in a single gear at 69F. With that intercooler, if you're at 86F today, you're going to be at the absolute limit in one pull if you're lucky.

I agree with you about the MAD 5" is for a stage 1, but your numbers are off. during all 4 runs, IAT went up 15 degrees, not 20. Considering stock rises by 40 degrees, that's a big improvement.
OP said he might go to stage 2, currently, he is on a stage 1. A 5" intercooler like the MAD is the best option for him right now.
If he goes to stage 2, a larger intercooler will provide better results.
i do not see a benefit in advising him to get a larger than 5" intercooler as it will add a lot of weight, cause a much a slower recovery, and turbo lag.
