gezz !!

You 5.0 boys are putting down some big numbers ..very envious !

 

Yes. They remapped the ECU. The guy from ECU Tuning Group in CA flew out to NY and installed the 1.5 lb. pulley and flashed the ECU. After 105 miles it learned the new program and had substantially more low end torque and throttle response. That's where all the fun is anyway. I didn't do anything with pipes.

 

Hey,

I was curious of your overall opinion of the tune. Is it rough anywhere or smooth through the complete RPM range? Noticeable gain in power? More then expected? How much was the charge for him to come to NY?


Thanks

 

The power deliver is very smooth and linear throughout the rpm range. At first it was hard to tell I was accelerating faster since it was so smooth but I saw how quickly I reached over 100 with just a little pedal effort. I can clearly feel it pulling harder. I didn't do a before Dyno so I don't know what the exact gains are but it was definitely worth it. There was no charge for him to come out. The tune was $1995 plus $200 for installation.

 

Did ECU tuning group install the S/C pulleys?

 

Not unitl 5252 RPM, at which point torque levels off or declines and horsepower increases. The basic formula is horsepower always equals torque multiplied by rpm, divided by 5,252. Horsepower cannot be measured, only calculated, and I believe there si a difference.
