Bosko's Z came to us from Las vegas with a few concerns, he had a lower pulley, headers, cai, meth installed and tuned at another place and went through a transmission (A8) extremely fast. He also noticed it would fall on it's face on the hit and slowly pick back up. He than contacted us and wanted to have us tune it and add a few more items. We quickly noticed in the file why the trans went out, torque was way under reported, knock sensors were basically off, and fueling was way off too. This was also causing his throttle body to close on him hence the laying over feeling.

We than did our upper pulley, ported snout, 17 lid, and retuned it. Now the car does exactly what it should do and he won't have to worry about the transmission anymore!

640/686.

So the car has upper and lower pulley on stock 1.7?

Cordes Performance Racing

yes, customer wanted to do both. it made a lot more low end then the other upper or lower lt4's we do. but up top it tappered off. On the cam lt4's we do we typically will do a 9% lower and our 2.3 upper and it works out amazing.

Aren't those numbers a bit low for what he has? Interested in how much the ported snout contributed

Cordes Performance Racing

Right on par with what we see. Cam cars here make 700 rwhp. Highest we've ever seen is 730 with one that we ported the blower and it was on e85 as well.
