I just ordered the SCT SF3 hand held tuner today. My question is what will I gain in hp and tq with the 92oct tune? I will have a dyno tune when all my mods are complete to maximize performance. Mods are in my sig.
I did a JLT CAI, high flow Bassani cats and full Bassani catback 2.5" exhaust...then I did the SCT tune and my seat of the pants dyno says it gained some compared to just the mods and no tune......but I spoke to Mike at BDP in lakewood, he felt a dyno tune is money wasted with just the simple mods......just an FYI
I have long tubes and off road x-pipe on order. I have under drives, and 65mm tb on the way. This winter I am going to have the heads and intake ported with stage II comp cams.
I haven't been on a dyno since I got my Livewire hooked up but I could notice smoother power and my friend said it felt faster then the last time he rode in my car. It also idle's smoother and I have gained about 4-5 MPG... I feel it was a worth while mod and it has a race fuel download that I will hopefully get to try out next friday.
I've hear that's the case with the 05 up Mustangs. You normally don't have to with a pre 05, but you may not get the max benefit, especially with several mods.
I just down loaded the "can" 92 oct. tune from SCT. The idle is much better with the tune. My C&L would be slow to return to idle. The seat of the pants dyno is very happy. The car is a bit faster. The throttle response is day and night. Over all I am very happy with the tuner. Now I need to install all my go fast parts and dyno tune it. I want to see 315rwhp and tq.
