before: Turbo Trix tune from August, no changes in hardware except for BR8ES plugs. This tune was knocking pretty good, so I made some changes



After: Added fuel to get rid of knock in higher RPM range



Took my wife for a ride to test her butt dyno, she says it pulls harder, she also said it "sounds smoother" not so rattly up top.

Also, the issue with it throwing codes hasn't happened since my changes.

 

Doesn't look like a signifigant change, but the fact that the codes stopped popping and that the knock voltage went from 2.5v to hovering around 1v is a big difference IMO.

 

yeah getting that knock down will definatly help you out, the car should definatly feel alot smoother. what are your mods by the way?

 

Wow, you can see from the BEFORE graph the torque tails off to 240ish by 7000rpm...

In the AFTER graph torque remains around 270 by the same rpm (7000rpm).

30lb-ft gain up top, I'm sure that's noticable! I hope I'm reading the charts right
