Thank you!Modified my mid-pipe to fix an exhaust leak at the collector and fit up around the transmission utilizing the original mid-pipe mount. Both items had to be finished up prior to the tune session. Also went ahead and changed the oil and filter while I had it jacked up.Appointment was for 8 am today about 1 1/2 hours away. Arrived about 20 minutes early. Stopped by Hardees right around the corner from the shop for breakfast. Pulled into the shop parking lot and parked. Look up and I have a Police Officer pulling in and stops right in front of me. (Knowing I had not broke any laws) I get out and walk up to the Officer's car because I couldn't hear what he was asking. Apparently he has never seen the Illinois Temp Plates before and had no idea what kind of plates I had on there....ok no issue here. Police Officer was super nice and left shortly after we chatted for 5 minutes or so.Talk to the guys that work in the shop for about 10 minutes, they pull the car in and start setting it up on the dyno. They give everything a check over and deem that everything is good for the owner/tuner to start working with. Bob (Owner/Tuner) shows up about 08:15 and asks for the build specifics. Develops a baseline tune to start with. Starts the car up and lets it get up to temp and starts to pull in 1st gear and he immediately shuts it off. He says there is something wrong but he isn't sure what yet. Asks his mechanic to check compression in both banks. End up doing a full compression test on all cylinders and a leak-down test. Drivers side compression is 190 in all cylindersPassenger side compression is 138-140 in all cylindersTuner deems that passenger side has jumped a tooth on the primary timing gear. (Said this happens sometimes on installation) Shop mechanic was shocked and said he wouldn't have guess that to be the issue because it runs smooth and felt fine when he pulled it in the shop.He cleaned up what he could with it running the way it was but it is not making any power like it should. Drivers side is running rich and Passenger side is running lean due to timing being off. Said the fuel is being sucked out by the exhaust prematurely. Only made 235 to the rear wheels. Said the setup should be close to 100 more when timed and tuned properly.It never ends.</blockquote>
