I have data of new FMIC in comparison to GearHead IC.
My first revision for this year commands 16 psi. I did a 3rd gear pull. I found a 16 psi log from last year with GH IC. Identical ambient temps. 57.20. What are the odds? So this is a very close comparison.
Difference is I start my log last year doing the pull at 36mph. This year I start the pull 48mph. So by 79mph I hit 51° IAT2 vs 57° ambient. In that run from last yeah GH IC...I was at 89° IAT2 at 36mph so it pulled longer WOT and hit 51° at 79mph.
This year new FMIC also 16 psi tune and also 57.20 Ambient temps I was already cooler IAT2 before I started at 71°. And bc I started the pull at 48mph WOT I had less time to drop IAT2 and I hit 51° 2 mph faster than GH at 77mph.
Is it better than GH? Not necessarily. Is it worse? Absolutely not. Is it cheaper? Yes! But it will probably do more damage than good for stock turbo guys. I assume it robs more WGDC% than GH. Also GH is direct fit. The FMIC required some familiarity with a sawzall! Lol!
More tests need to be performed. But as far as first look it looks great. And for a comparison scenario...same ambient temp, same commanded 16 psi...couldn't ask for more.
I wanted to make sure it didn't underperform GH and it does not underperform. Goal met. Now let's find out what it's capable of!
GH has the nice linear IAT2 drop and is labeled Rev16. FMIC is labeled Rev21 and has more of a sharp IAT2 drop...interesting is that IAT2 went back up for a second. It'll be interesting to see what changes if any Brad makes to the tune...equally so what he thinks. Still waiting for a response.
