What kind of unit is it? If it's a "brick in a bath" cell, add neutral plates.
If it's a dry cell, add a plate...this will reduce the voltage each plate sees.
Making your electrolyte solution a bit weaker might help, but it would reduce gas production.
You could also add a PWM, but it would have to be custom built, mainly because the ones available won't handle more than 15-20 amps

RE: OVER HEATING PROBLEM
130 isn't too bad for some designs. What type of unit, how much output, and is that on the bench or in the car?

RE: OVER HEATING PROBLEM
Yeah, you wish. Heheh, we measure in litres...and I think you meant 1.5, not 15.
Very odd it would stay at one amperage too. That just doesn't happen that I've seen...in hundreds of units posted. The nature of the electrolyte is that it increases in conductivity as it gets warmer.
Perhaps you have discovered an unknown electrolyte?
Following that, there are the methods of testing, such as fillup requirements, output measurement device and method, and all other parameters of study required for consistency.
I.E.; I fillup at the same pump, face the same direction and stop at the second click of the nozzle. I test output using only the vehicle for power with unit warmed up (except for expermimentals), and use a measured bottle in a potfull of water along with a timer and put the hose in exactly one second before mark (you lose about a second getting it in). Then mark at the first bubbles escape from neck of bottle. Amps always measure from the vehicles installed ammeter. Temps are measured with a laser thermo.

RE: OVER HEATING PROBLEM
Ben, help me out here. I looked up a conversion table and 15 gallons is about 56.86 liters. Thats about .95 lpm based on your info. (115 liters per hour is about 1.92lpm). Close to 2lpm is pretty darn good if thats the case. It would be nice to know more about your cell design and actual output. If you have read the posts on this forum, isn't much these fellows haven't built, are building, or will build. Also would be curious to know more about your electrolyte, unless it is a secret formula. Anyway, folks might be able to help with some better info.

Would appear to be much better than my special chemical additive which only gives me 2 parts hydrogen to one part oxygen from water.

Swap secrets?

My additive is NaOH. Works on accepted standards which gives water composition as H2O, two parts hydrogen to one part oxygen.
Are you using heavy water by any chance?
