question is that i have 880 cc in right now and just bought 1200 now if i put the 1200 in will it run like 880 or will it run to 1200 potential without flashn the ecu..another thing is that i have to drive 130 mi to get to the dyno should i just wait til i get there to put them in or would it be alright to install them and drive down there without it hurtn or damaging anythng?

 

Its gonna run like crap way too rich. Wehn you run too rich you could damage the engine cause too much gas is washing away the lubrication at the cylinder walls ,130 miles is a lil bit of a drive. wait till you get there its better than being sorry.

 

alright ill wait
