Etc adjustable throttle controller

I have to call BS on tuning and say it is a ploy by after market companies to make money. Adaptive ECU's have been around since the 80's and yet for some reason only domestic and euro cars seem to have the option to use a laptop as a tuner. This is the main reason why I will NEVER buy an Asian import as a performance car. I see no reason why I need to drop a grand on a stand alone ECU when the stock unit is perfectly capable of handling basic tuning. As for power increases, I gained around 9 RWHP on a stock LT1 Z28, add in intake and exhaust that number increased to 27 RWHP. I was also able to adjust my speedo for tires, lower my coolant fan activation temps, and monitor my engine's performance at all times. Since the xD is tuned to 87 octane I have no doubt their would be a power increase if a 93 octane tune was installed.

i doubt its ploy as the aftermarket company... as far as i am informed the new toyotas use a 64 bit ecu.... which is constantly relearning the way you drive.... perfect example is the 2nd gen xb.. those running turbo's are having problem with the ecu not working all the time.... as the ecu adapts to wha the fic are doing... so it requires them to reset the ecu from time to time... as far as comparing your american v8 to a 4 cylinder econo car is like apples to oranges... even stock they have to detune that v8 to adhere to local and federal emission laws.... so hence changing the intake and header will yeild more power... were as these econo cars are already running at pretty much its max efficiency to keep gas and drivability. as far as 93 octange goes the xd doesnt do very well with anything besides 91... there were pics of a motor that has been running 91 since they purchased and and there was alot of residue as the motor was not burning it all....

The reason so much residue was in the engine is because of the tuning since the engine is set to run on 87. I promise you a good tuner could get an xD to run on 93 without a residue left behind. My LT1 V8 was probably running closer to max then the 4 banger in my Scion since the engine was designed to run on nothing less than 91 octane and the timing was already fairly aggressive. Plus as far as I can remember even the older Asian cars had to run on an after market ecu.

That was my xD, and I agree that with a good tune it would burn more efficiently and offer more power... I would like to note as well though that running on 87 octane as appose to 91-93 octane is noticeably different, with the higher octane fuel, the xD is much, much peppier...

Try 91 octane for a couple weeks and then switch back to 87...

I think you feel a difference between using 93 and 87. I even feel a difference between having a third of the gas tank full and a full tank. feels as if it responds better and better exhaust note imo lol
