    How are you rewiring the harness in your door?

    New door wiring harnesses are available (I am sure VPA can get them). I always replace them. Repaired ones seem to go bad again and I have never had a replacement go bad. Must of done 50 of them.

    Help with Cat Delete Codes (420 & 430) 0n Gen. IV

    Your best bet is to change to the Mopar Performance Controller. It has a calibration that works well without cats and the check engine light will not come on.

    Oil Pan Gasket Question/Observation

    It could be the rear main seal cover gasket, I had this issue on numerous 1996-7 Coupes as the gasket material had a defect that made it shrink. You think the oil pan is leaking because there is oil there. Have not had any issues with the aluminum gasket.

    Low Cold Start Idle and Stall

    This could be an idle control motor issue as well. The IAC motor does not want to work when cold, if your battery checks OK this is most likely the cause.

    99 ACR w/ exhaust dyno results

    Your numbers are in the range they should be. Stock engines can vary about 5-7%. You could get some more power with a custom tune. If you run on 91 octane fuel then do not get a 93 tune. These engines are very knock sensitive. A tune with more timing may feel good down low but can damage the...

    do gears actually increase HP?

    Changing the gears does increase the applied torque to the wheels, torque gets you down the road. The first Cummings truck Dodge put out made 150hp but 400torque. Lower gears do not help unless you can get traction, so consider a better posi when you do a gear change.

    SRT Chat is now LIVE at >>>

    Can you comment on the new race Viper and how it differs from the original GTSR. Is the engine displacement the same as the the standard engine? Will these cars be available to private race teams? Thanks for all your great work. Dan

    Recall on 06 viper headers?

    Your manifold most likely has a crack. Best repair is to remove it and have it welded. Once rewelded they never crack again. Engines that are cold started a lot and driven short distances seem most likely to have this problem.

    How Earth Straps Increase horsepower

    I did find that grounding aluminum radiators reduced oxidation and corrosion. My 2 cents, if it helps.

    Engine misses some backfiring

    I think you have made the right call on the plugs and wires. Here are a few tips. If you have access to compressed air then blow all the dirt and dust from around the spark plugs when you remove the wires. This keeps dirt from falling into the spark plug hole. When installing the new plugs use...
