Guys,

I need to upgrade to a new engine and I'm pretty much an Intermediate when it comes to engine tuning. Anyways here is the link of the Picco that I'm interested at.

The one that has a purple heat sink and it cost $119

Is it Easy to tune???

i would suggest on spending a few more dollars and get the JL Red Dot,wich is a picco also but its a much better engine and the difference is only sixty dollars,but is worth it ...

I have found the Roar Legal Picco to be very easy to tune and set up at the track for the conditions. I am racing one now, and my son has one in his car also. You can keep up with the faster cars on a short to medium track. You have to get on the power early, and if you miss a beat the OS TZ's and the like will overtake you.
The JL Red Dot from what I have read is very fast and competitive with the fastest performance engines at the track. Like Roniel_R stated, if you can afford the extra cost purchase one.
For carb set up/tuning just keep it on the rich side and you'll be ok.
