aerobear - How much additional horsepower \ rpm does the tuned pipe give you on the DLE 20?

kiwibob72 - I'm relatively new to gas, too, but I believe you should be able to starve the engine using the throttle (same as Nitro). Many also install optical kill switches and others (like myself) also install a choke servo. I prefer using the choke servo, as its' quick, you don't have to re-find the spot where your throttle was before, and the engine starts right back up. (kill switch will do the same).
