Wanted to send thanks for the Magnaflow cat-back system I bought from you prior to Christmas. Love the sound and the look over stock. Now if I can just get it broken in and get rid of that 'new' smell. Anyway, onto the point of this post.

To refresh your memory, I drive a 2001, F150 SuperCrew, 2x4, 5.4L. I've installed both the Airforce One intake kit and now the Magnaflow SISO catback (#15609) system on my truck. I want to move next, per our previous conversations, to the Micro-Tuner. Here's my question. I live in Orlando, FL, right down the road from Sanford, FL. Does your Sanford facility have a dyno that I could get my truck onto to set a baseline before I install the Micro-Tuner program? I'd like to know where I'm at before and after the install. I know you had a thread out here a while ago that had something to do with recruiting potential test vehicles. I didn't know if I could get into the Sanford facility under this 'testing' process.

You know, it never hurts to ask, right? Let me know what you think.

Thanks again for all your previous input.

 

Hi BigDeal,

In short, you'll need to find a public dyno facility to put your 2001 vehicle on, it's not a candidate to go down to Superchips. And you'll have a hard time finding a dyno that can really do these heavy trucks right, the typical Dynojet & other inertia dynos will virtually always read too low, as the load factoring isn't right, they usually have a pair of rollers for a 3600 lb. static load. For the supercharged Lightnings it's just the opposite problem, the intertia dyno's generally read too high, many times by as much as 30-40 horsepower.

Overall, I wouldn't think of chassis dyno's as some dead-accurate or even close to accurate device for measuring absolute power; they vary *widely*, as do the operators experience & techniques, etc. To us, a chassis dyno is only a tuning tool, nothing more. We're far more concerned with the actual improvement in *performance* of the vehicle, which can easily be checked with a GTech Pro (use the new Competition model), than what a chassis dyno says. The main thing we use chassis dyno's for in these heavy vehicles is just a platform on which to do A/F ratio testing.

The only time we'll send a vehicle down to Superchips is for needed R&D, and that happens only for new model year vehicles, when we'll need to see a few bone-stock examples, and then some supercharged examples, etc. At this point, we don't even have a need for 2003 F-150's, except the Lightning & Harley models which were only recently starting to be delivered to dealerships. By the time a couple of model years have gone by, as in the case of your 2001 model, the R&D has already been done, long ago.

If you want to make a better investment in your ability to get some measurements of performance improvement, give yourself the ability to do this any time you want, on an ongoing basis without the recurring expense of a chassis dyno every time you go......... just pick yourself up a G-Tech Pro Competition model, they're cheap & work well for measuring performance. By the time you pay for 2 dyno sessions, you could have owned that GTech Pro Competition model.

Glad you're enjoying your Magnaflow exhaust, it's always nice to have only the very best parts on your truck.

Have fun,
