To fully all out tune your car whats the best one you guys are using.
if you already have an Xcal the obvious choice is SCT, it is widely used and most tuners will at least give a pointer here and there.
If you do not have a handheld or you have more than one care to tune Sniper if a good choice, instead of having to buy an xcal/chip per vehicle as well as the ECM strategy you buy the ECM code template and can load multiple vehicles on the interface device and if you run out of room you just back them up to the PC.
I started tuning my car with a friends Sniper setup but will be getting SCT soon since I already have an Xcal and have the car setup to datalog through it
i actually have datascout and delta force tuner already but would not mind changing over to a better one. but if delta force tuner is god ill stick with it.
