Scoobiedoobie, When i tune my nitros, I aim for a slight load up in about 20 seconds, crisp launch and a max out in about 5-7 seconds. Don't know about the Power factory engines, but my engines run from 250 with my 3.3 traxxas to 230-240 with my Racers Edge .32. tuning is all about practice and patience (believe me on the patience) I have spent two years playing with Nitro and am finally to the point to where i'm confident enough to try to help others. The first thing i'd do is go to the factory settings and work from there. Use the temps as a reference, not a guidline. When it starts to run good to you're tastes check the temp and remember it, but don't just go by it, the weather can have a serious impact on how it runs from day to day, so it could run warmer one day and cooler the next
