Im not a fan of fully relying on meth for big power. If you run out or your meth system malfunctions, kiss your engine goodbye in that scenario. An OEM-style HPFP will be way more reliable than a meth pump every single time. In my experience, replacing a meth pump every year or two is not uncommon. I don’t mind meth for some extra cooling and a little extra fuel, but fully relying on it every time you boost is not a great idea in my humble opinion.
Finally someone who realizes there is something terribly wrong with relying on Meth for 50+ extra horses. It’s like an epidemic, I can’t even find someone who did the LT4 HPFP and LT4 high flow injectors on the LT1 without Meth, so I can see how many horses they pick up with that alone

How difficult was the install, and what all was involved in putting it in?

On my old setup we opted for using the alky control dual m15 nozzle kit and sprayed more meth for 680 whp with the stock LT1 HPFP.
