Unlikely Result

After the installation of the ported throttle body and fine on-the-road tuning, I am enjoying better acceleration and high end power. I was testing how my fuel efficiency was and it did proved to be better than when it was completely stock. I am very happy with the results and was planning to go for a dyno power run to find out what is my new power output.

During my last tuning, my Celica achieved 149.8 whp and 15.48 Kg-M of torque. Now that my Celica is faster, I imagined my coming power run would result in at least 153 whp and higher torque. When the day came for my power run, I was very excited and called my friend to test his Celica too for comparison. The result was out and I only achieved 147 whp at the highest but the result printed is 145.27 whp with 14.53 Kg-M of torque. I was surprised by this low number.

After

My friend's result was 142.25 whp with 14.26 Kg-M of torque. He had a more enjoyable time than me especially since after all the mods I have (Management unit, ported throttle body, air filter and muffler), I only manage to have a 3 whp differences. Luckily, so far I have been winning drag races with him. This causes him to have the urge the mod. I took the opportunity and sold him a Camcon unit. I should be worry about him winning me now but I'm more towards earning profit of him.

Thus, in conclusion I could only say this is the difference between on-the-road tuning and dyno tuning. The conditions are different and each gives a different style of tuning. Personally, I believe on-the-road tuning is more realistic and the feeling you get when you drive is the most important. The numbers and graphs is just an indicator. I believe in my tuner and I will not let this result to bring me down. I know my car is more than what the results say.
