    I got new tires (taller) and need to recalibrate speedo. Are there any pprogrammable modules that have preset programs? I want to improve mpg before taking long road trip. Any suggestions. Thanks
  • Hey there folks! Just got my 2005 Victory Red 2500HD Crew Cab 8100/Allison today. And im already looking for aftermarket things for it. Im planning on putting two 26 in Hadley and two 24 in Hadley airhorns on it, true dual exhaust and maybe a superchip.

    First off, what exhaust system should i use? I'm thinking about getting two flowmaster series 40's (I want a very deep and loud sound coming from my big block monster) I hope to announce my coming with those, and then to reinforce it with the 4 air horns.

    I have been looking at Superchips, but im not sure if i should do something like that. Will it damage my engine any, and what kind of power gains should i get. 330 hp to maybe 360? 450 torque to 500? Tranny damage doing something like that? (i wouldnt think so since the Duramax makes 605 torque but im not sure)

    and also my truck has the towing package which puts option k47, the high capacity air cleaner on. I have always used drop in K7N filters before this truck... should i with this one?

    Thank you

    I think Flowmasters do a good job but keep in mind that you could grow very very tired of the noise if you pick a system that is too non-restrictive. But maybe given what you are driving you are fairly noise tolerant? Anyway, it would be great if you could take a spin in a truck similar to yours that has already done this. I wish I could give you a heads up but I don't know anyone who's done this on the Duramax.

    You want 10% horsepower increase from a chip? I don't think that's realistic. Have you seen such claims? Let us know with a URL and we'll check it out.

    As for air filters I personally think simple "drop in" filters are useless---you'd need to consider a ram effect or cold air intake to get anywhere I think.

    Anyway, the air horns sound like a great idea (I wish I had some for my Porsche) and the exhaust setup may work out really great for you---wish I knew more about that particular application. We need to do some homework, right? But I'd wave you off the K&N and as for the superchip, this needs research--there's a lot of stuff out there that just doesn't deliver as advertised.

    Maybe you could work out a deal where you buy the chip and dyno it yourself, and if it doesn't show what it's supposed to, then return it and get your money back. You may lose the dyno fee but at least you haven't blown $300 for nothing and maybe even a LOSS of power or fuel economy.

  • i recently purchased a 2005 celica gts, and i really love the car. i plan to turn it into a street racer but i have a few questions first. it is a real chore to find parts for a 05. are parts like a cold air intake, cat back exhaust, coil overs, and turbo kits interchangable with the 03-04 celicas and the 05 model. all of the companies only sell parts for up to the 04 model. any help would be greatly appreciated. thanx. jc

    Have you checked with TRD yet?

  • Thanks for the input... im very tolerant of the reverberation so i think i will be ok with that. (i had a 79 ford 351 with no exhaust on it... that was loud, but it didnt bother me) (that truck also had two 26 inch hadley air horns on it... they were really dern loud... so 4 should be even better!)

    On the old superchips page they claim that the 8.1 liter V8 should... or maybe they should say could get about 30 extra hp, and 40 extra ft. lb. of torque. I called them to speak person to person and he told me the same thing. (i think expected gains would be hard to really concretely say, but i like the idea of 30 hp and 40 ft. lb, for that. what do you think?)
  • Mr_ShiftrightMr_Shiftright CaliforniaPosts: 44,408
    Well what's the guarantee. Will they guarantee the truck will dyno out an extra 30 HP? do they mean at the flywheel or the wheels by the way.

    I have a 99 Sebring convertible and would love to get 20 or 30 more horsepower. Any suggestions? Including things other than an aftermarket chip.
  • mmoyermmoyer Posts: 5
    By the way, the 99 is a 2.5liter, 168 hp

    CAN ANYONE TELL ME THE CORRECT FIRING ORDER FOR A 1999 DODGE RAM 1500 PICKUP? MY BUDDY IS HAVING PROBLEMS AND DOESN'T KNOW WHAT THE ORDER IS. THE MOTOR IS A 318. ANY HELP WOULD BE GREAT!!! :cry:
  • fredmcmurrayfredmcmurray Posts: 215
    I haven't found anything specific to the 1999 318, but every Chrysler V-8 I have seen is 1-8-4-3-6-5-7-2 .

    HELP! Last week I took my 01 Cadillac STS to a mechanic friend for a new exhaust system. My car ran great before I took it in, now it is having problems.He assured me that he could use a magna-flow catalytic conv., and mufflers. I think that I should not have removed the cat. My service engine light stays on, gas cap indicator light comes on, not to mention that I had to replace the fuel pump,idlemotor for surging,the oxy sensors said that gas/air mix was too lean??? I have to take it back tomorrow, feels like it is missing! What do I do?

    i have a 86 pontiac grand prix V6 3.8. I want to increase the power without replacing the engine. I need some ideas. I would like to see more of an increase in take offs.
  • qbrozenqbrozen Posts: 17,148
    There's gotta be more to this. I am assuming at this point that he replaced components which originally had oxygen sensors in them ... not sure why you'd get the gas cap light, though.

    Well, if nothing else, sounds like you should consider going back to stock ... at least with the cat.
