I was wondering if anyone has the performance combo I'm interested in. I have a Volant CAI right now and I want a Hypertech PPIII and MAC after cat exhaust to go with it. Will I get any signifigant gains with this setup or does anyone have any better suggestions for the exhaust. Single over dual or dual over single. Any imput will be helpful. thanks.

All I can say is search the forums in lightduty and try something. As you can see by my signature, I'm still looking...been so for months. Don't know if single 3 is better than dual 2.5 or 2.25 and which one keeps low end torque and economy.

I may not be the best one to answer this, but I'll give it a shot since I've just had my exhaust done last week. For my stock setup, it was a 2 in 1 out with the 2 in being 2". I converted it to a TRUE DUAL and the out pipes were 2.25". As the guys at the muffler shops suggested to me, go no more than .25" on whatever setup you run. This should leave you with some backpressure and won't have your computer throwing codes. I would recommend the following: 1. If you have true duals then go with duals all the way out. 2. If you have a single you can a muffler with a dual out. 3. You could do a single in/ out.

On the dual in theory, you could have a 3" single and that may help your bottom end.

 

Anybody else please feel free to correct me or to shed a better light on the question at hand. :thumbs:

i would put money on a BBK 80mm TBI and set of 15" 282FLE flex-a-lite cooling fans being the biggest gain without going to a supercharger. i did the TBI and am about to try the flex-a-lite fans next. here's the manufacturer's claim:

With our Dual Electric Fan, you can expect to gain up to 17 or more Horsepower and roughly 20 ft. lbs. of Torque. Impressive gains for both towing and performance. Available in both push and pull options, this light-weight monster has dual 15" blades that move an unbelievable 5500 CFM. That’s serious engine cooling power. Our Electric Fan will also increase your gas mileage, save you money, and actually pay for itself over time. In addition to performance gains, you’ll also notice how much quieter your Electric Fan operates. The obnoxious roar and squeaky belts from your mechanical fan are eliminated. You get quieter, more efficient operation.

Dr,

 

 

I think there are better choices for programmers out there than the HPP3. I used one on my Camaro and did before and after dyno's. Didn't gain squat. The Westers reprogramming gets nothing but praise from what I have heard.

 

As for Mac, I've used their parts and the quality sucks. I would never buy their stuff again. My vote would be for Magnaflow.

      Did you ever get this worked out? Mike is doing the two start thing now too. This is after a new camera back in December.

      AFM Disabler Question

      By KARNUT · Posted

      I’m doing an experiment on a vehicle I don’t have much money in. I’m going by the premise that after they last 100K miles they were no mechanical problems with assembly. Or defects with the parts. With oil changes by the minder for the first 127K miles when I acquired it. I quickly went through low mileage oil changes then settled on 5k oil changes with close to 170K miles on the vehicle currently. I did have the option to turn off the cylinder deactivation. I didn’t on this vehicle because it’s in ECONOMY mode at least half the time. It should be a no brainer frequent oil changes are the key. The manufacturer gets away with the long oil changes with its severe service  maintenance. Just ask them what is normal.

      Hot air constantly blowing through floor vents, drivers side only?

      By baglie1 · Posted

      Even set to "recirculated", the air pushes out and is hot. I have noticed that sometime it doesn't want to switch between recirculated/vented air. Say it is set to Circulated Air and I want to switch to Vented, when I click the Vented button, it just quickly lights up/clicks and immediatly switches back to Circulated. It's done this a few times now. So maybe it is an actuator getting stuck? But then, that doesn't explain the hot air when everything is off does it?

      Gas Prices

      By Chuck FB · Posted

      I wonder what the price is out at the coast, Big Sur or other out of the way locations as I bet they are charging quite a premium over the in land pumps.

      2 speed transfer case optional now?

      By Chuck FB · Posted

      Were you looking at the HD trucks on the GM website or the half tons as that makes all the difference. As far as I know there are only two options for the HD trucks and that is the standard 2 speed transfer case or the 2 speed transfer case that has the added 4 high auto feature and they put that transfer case by default into the LTZ and High Country although its optional in the LT and not sure if its available in the work trucks.    The half tons, that is where its been a total mess in my estimation for a few years now with most trucks below the top trim having the single speed transfer case as standard but with the option of having the two speed such as one would get by choosing the Z71 package, however then not being able to get the two speed transfer case with the towing package unless it was a higher trim truck AND had the 6.2 gas so one could combine the towing package gearing diffs with the two speed transfer case. Having said that if its a trail boss package then it gets the two speed transfer case but not necessarily able to get the tow package as it would depend on trim level and engine chosen. Believe me, people have bought the GM half tons assuming "of course it will have a two speed transfer case" only to find out after when they really pay attention to what they now own .... crap, there is NO low range !.    I don't believe Ford or Ram have gone that way yet with their half tons but like I say its been a few years now that GM has done this with the half tons.
