Welcome! Very nice fox!
You've got some nice upgrades...particularly with the tko! Nice supporting engine mods with the intake, tb, and injectors. As always, the heads are going to choke it down considerably. A bigger cam would be icing on the cake, but you could get by with some 1.7 rockers, which (iirc) will increase lift by 30%. Luckily, you have a 90 model, which means it has maf as opposed to the older speed density system. Maf is much more accommodating when it comes to performance mods!

Just curious, but did you add the engine upgrades or did you buy it that way? I'm wondering if you're sure the heads are stock? Gt40 iron heads are a common upgrade and can be easily overlooked as stock. World Products iron heads are less common, but can also be overlooked, since they're not aluminum.
Any chance the heads have been swapped?
