Do you run a controller for this setup. I’ve looked them up and thought about it but haven’t run the water meth in like 4 years so I never ended up buying a controller as it would have been a waste of money to buy something to control a system I don’t use lol.

I'll guess 20+ and over 800. You have one of 3 choices IMO - better intercooler (lots of $), E85 or methanol (E85 is difficult to get at consistent % and methanol is $x2), and lastly - meth/water injection (cheap and easy).

I run meth injection. Look at the graph. I came to a stop, let off the brake and went WOT to 3rd gear (street tires.) You can't see the intake temp (MAT) at zero mph, but it was 127. In about 4 seconds it dropped to 83. The meth turns on at 4psi (125kpa) and full on 8 psi (153kpa). You can see it's quite effective.

p.s. - I run 50/50 boost juice at 15 gal/hr and it actually adds fuel. So with the street tires spinning (less engine load) and lower boost (below 12psi) it fattens the AFR somewhat - into the mid to high 10's. If it's not spinning it sits in the low to mid 11's.

EDIT - that screenshot isn't very legible <img src="" border="0" alt="" title="sad" class="inlineimg" />
