Are the stock DV's in a 215 pump an upgrade to a 160??

And what set would be best for towing @ 300-350 rwhp? I'm guessing 181's but I have no freaking clue...

Yes I believe that they are.......

181's are the stock delivery valves in a 215 Pump. 191's would give you a bit more fuel, and more EGT problems than 181's. You could run 191's if you watch the Pyro on long hills, then again, you could run Laser Cuts if you watch the Pyro all the time. It's all up to you, stay away from L/C's, you don't have enough air to support them.

the 181's gave me alittle boost in power, not EGT's. There a good choice for DV's in the small pumps to support bigger injectors.

your 160 pump has 131dv in it. The 181's will give it a boost in power however I hope to have some 191's installed pretty soon. Mybe cumminsdriver will give somefeedback he's running 191's in a 160pump and likes them as far as I know.

I can tell you from my experiance that most d-valves do give you some bump in power and boost. I will also tell you that there is a penelty that comes with them also and that is higher egt's.......

What about 022s. I would like to go bigger than 191s but not all the way to LCs.
