We picked up 137 RWHP on this GTO. The first step was removing the detailing towels in the airbox for a free 37 rwhp, then we added a Texas Speed 233/239 cam, LTH, MSD intake, and OTR intake manifold. After dialing it in on the Mainline Dyno, we hit 437 total RWHP!

This Camaro SD came in with drivability issues. We found a broken MAP sensor, broken map sensor wires, broken flex fuel wires, and broken #7 ignition coil wires. After fixing that and cleaning up the tune we have the drivability right where it needed to be!

We are looking to fill two new positions at Greg's Tuning Operation!
The first is a Sales/Marketing position. This position will be responsible for sales, website updates, and social media and marketing. Position has some flexibility. Pay negotiable. Candidate MUST be familiar with automotive and preferably performance.
The second position is a dyno/tuning assistant. This will start off with prepping cars on the dyno, with a future goal of an assistant tuner to help speed the tuning process. Pay is also negotiable.
If interested in either position, message this page and reference the position your interested in.

Super clean GMC in with cam and bolt ons for some dyno tuning! This truck now holds our 5.3L NA dyno record with a super simple combination but a very large cam for a 5.3L! We look forward to seeing this one back with more goodies!
