Save your pennies and buy a larger turbo :thumb:

I have never liked the idea of filling my CAC with an explosive gas. :eek:

Not many run it none that I know of. As far as power they say it adds up to 100 HP , I never got close when I had a propane system on my truck IIR is was more like 50. I only ran it for added power not for MPG so I have no data but I assure you that the gains if any would be minimal. You'd get better running a tow tune as by the time you figure in the added cost of the propane at fill up.

I wouldn't bother. If it was worth it believe me more would be running it.

Propane is a pain in the ass, not worth it IMO. I have enough issues just keeping it running good never mind injecting a highly flammable gas in the motor;)

I ran it back in 2005 on my 02 GMC and you could tell when you turned it on, gave you a good hit of power, egt's went up quick and in the end I popped a head gasket. Not sure if it was that and/or the 50/50 water/meth, and/or the stacked tuners or a combo of all three/four.:D In the end the head gasket went and the rods got short. Cylinder walls were so heat scored that the block wasn't useable for a rebuild. Besides the propane tank was heavy as hell.;)
