I'll install my 70mm TB soon. I just need to get some different bolts. The bolts in the Damond kit don't work well with the FP Throttle bodies.
Are there any dyno results with before/after the TB change?
And only TB change, without retune?
And without changing pipes at the same time?
+8 hp / + 40 ft/lb on an ST posted in link several posts above, however this had a CPE cold side pipe AFAIK:Of course, pipes before tb.
But it would be nice to see the improvement if the TB alone.
A friend has done it, with sirtec pipes and 63mm tb. The car felt like lower torque and power. But his setup is also with tb Spacer and manofold spacer.
He removed the 63mm TB because driveability/power.
Thats why i would to see only differences of the TB.....
