I have a 03 Lb7 cc sb with a Volant intake, MBRP 5” exhaust, Banks big head waste gate, PPE boost increase valve and PPE excelerator tuner. Iv got a rancho 4” lift with 33x12.5x17 dick cepek fun country rubbers. Iv been enjoying this set up but seeing as I am in the military and now am driving a lot more after the wife and I were stationed at separate bases about 500 miles apart I was looking at water/meth kit for better mileage and better performance. Wasn’t sure if anyone had good experiences with doing this or had a suggestion for a good kit or even a kit for sale second hand. Thanks:saluteusa:
