    Hey Guys.
    1999 Trans Am WS6 6-spped
    Stock LS6 Heads and Intake
    228/232 112+5LSA cam
    Pacesetter Headers
    Borla Exhaust
    MSD 8.5MM Spark Plug Wires

    So I put the car on the dyno to have it tuned and there was liek 1.9% knock after it all, so it was suggested I changed my spark plugs, Yesterday I took it to the mechanic and he took out the stock AC Delco PLugs (That were fuckt) put in NGK TR55's, now it runs like shit. Lost a fuck load of power, it like, crawls around ok but if I try to pick up any speed it's sluggish as hell. I know it could be a variety of things but I don't want to go back to the city (100miles away) pay $125/hr on the dyno to find out the plugs are either gapped wrong or are too cold for the car.

    Do you guys think I should take it to like Canadian Tire or something to see if the plugs are gapped right? Or should I just think that the old plugs were that fuckt they threw the tune off when I put in new ones?

    I have tuned my car with sht plugs and when we changed them it didn't make that big of a difference, If anything it ran better. We did a little more tuning and got a little more but not much.
    Another problem is dyno tunes. That screwed up a set of plugs on me because the cars was always running rich and I have driven in old GTO's and Mustangs and that can't compare to the fumes I had coming out. People behind me complaned on cruises. Using a dyno is ok but have them set it up more like a street tune than a WOT dyno tune unless your always going to be at a track. Alot of people I know had their cars reedone because they were to rich.

    I would lean towards, one or all of your plugs are gapped wrong for the tune, Or your mechainc left a wire loose, i would pull all the plugs and check the gap on each plug and ensure each wire is good and tight and not melted.

    Hopefully the plugs are fully threaded into the block and weren't left loose. Very easy to pull each plug wire, check the plug torque (11 ft.lb.) and then re-install it to ensure a good connection. You want to hear/feel a single click connecting the wire to the plug and a double click connecting the wire to the coil. Another thing to look for is clearance between the spark plug boots and headers -- it's possible that you cooked a wire or two on the ride home.

    Hey, i have it in today getting everything checked and checking the gaps, def something wrong wit the plugs or wires. No lights are coming up. Just slugish as fuck when i tramp on it. I told them at CT to make sure the gaps were .040 - .046(recommended by my cam maker) and to make sure wires were all tight and not broken, etc etc.
