Owner : Kyle M

Car:  ’99 Sunfire 2200 OHV

Story:  After installing numerous bolt on modifications to his car, Kyle wanted to ensure everything was running correctly, & that he was getting the maximum potential out of his mods.  A custom in car tune  brought everything together for him.

Virtual Dyno results,  109 whp & 137 ft/lbs., vs. 101 whp & 131 ft/lbs untuned.  A gain of 8 whp & 6 ft/lbs.
This run also hadn’t had the timing increased to what I would normally run in an LN2 car.  Issues with the car’s knock sensor prevented the car from seeing full timing.  I would expect to have seen probably another 3-4 whp with some extra timing.
Assuming a 15% loss through the manual transmission, crank numbers would translate to 128 hp & 161 ft/lbs.  Quite an improvement from a stock LN2’s 115 hp & 135 ft/lbs.

The LN2 seems to have taken to tuning nicely.   While doing our pulls in third gear tuning the car, datalogging shows the car to be 3/4 sec. quicker from 60 – 130 km/hr than the stock tune.  That is significant!

Customer Comments:

“Just wanted to say great job on the tune – very noticable acceleration and torque upgrades.”

“I have noticed an increase in fuel economy!  Before the tune I was getting around 23 mpgs.  After the tune i have noticed a 3-4 mpg increase in fuel effeciancy putting me up at 26-27 mpgs. AND THATS DRIVING THE SHIT OUTA IT. If I babied it I bet I would see another couple mpgs.
