Well I just got my GTO back from precision motorsports. Had them install some fun parts on the car Listed below.

Mods.
Magnacharger
Precision Power-3 Blower cam
Corsa Touring Catback
SLP 160 Thermo
LPE CAI.
Tune with HPtuners.

Previously Installed:
Kooks Coated LT Headers
Catless Midpipes.

The car is a MONSTER. Here are the results.



517.6rwhp/455.2rwtq

Definately taking my time getting used to the new power.

Old power was 343rwhp/346rwtq with just headers and a tune.

 

Congrats on the results. That is an awesome torque curve. Gotta love the maggie

 

What's the diff between red and green graphs?

 

red was just a very basic tune so that they could get it to run decently with the new supercharger and cam.

There was another pull in between these two that was 507rwhp/451rwtq

 

Nice #'s!! I want to get a LS2 Goat for my wife, but the bitch likes mustangs better

 

have her test drive both of them . Last time the wife wanted a car I made her choose 5 other similar cars to test drive...ended up getting a Dodge magnum instead of a toyota matrix because of it.
