i am thinking about putting a propane injection set up on my truck, i am also considering a 6 position chip. my questions are would you still only be getting only about 70 horse from the chip with the propane not including the propane power, and would there be any downside to mixing the two? Also about how much horse could i expect from propane?

 

Never ran Propane and I don't intend to...

Don't think there are any guys on here that run it either...

Power from just the chip will be in the 60hp range because you can only put so much fuel through stock injectors...

 

...but you can put a whole bunch of connecting rods through the side of the block with propane.

 

That's why I said I don't intend to run it... Heard too many bad things...

 

The OP mis-spelled propane... The correct spelling is proPAIN...

Dont do it, its a big fat no no...

 

ok thanks for saving my engine guys, sounds like no propane for me, i didnt realize it was so bad for your rig.

 

Its not bad when used in VERY small ammounts for MPG gains only. But people get greedy and turn up the regulator for power, then your timing goes thru the roof!
