CAI / Tune
Hey All !
Where is the power in these puppies?
I have some of my Mustang CAIs laying around... maybe I can make one of them fit...?? Any good? Tune needed? I do have an X-Cal available...
Truck came with full exhaust...
I just want some more up there so she won't have to down shift uphill...??
Ideas??
Thanks!!

Give us call and we can get you all the power you could ever want, that is what we specialize in.
However, you can forget making it never downshift going uphill, as that is not going to happen with anything less than a positive displacement blower and gears. Now we can certainly make that happen less thru tuning and letting it breathe, but remember that you have a non-PI unit there in that 1998, and so it's a heavy truck with a poor power to weight ratio.
Cruising at say, 70 mph on the Interstate, your turning the motor maybe 1800-2000 rpm, and the motor is making maybe 80-100 HP at best - so it's going to downshift trying to move 2.5 tons up a grade, of course. We can't expect it to stay locked up in a negative torque multiplication final drive ratio and not downshift going up some grades.
With our tuning, it will stop a good bit of the downshifting just due to the increase in torque on part-throttle, but there are still going to be grades that it will downshift on, the point being simply just to not think you can make it *never* downshift going uphill - yes, it can be improved so that on some grades it doesn't downshift - but there will always be some grades where it will.
And of course, this will of course depend on where you live and just how steep the grades really are - you probably already know all of that.
And yes, it needs to breathe - just don't do anything that changes the location or position or orientation of the MAF meter, as that will throw the system lean and require a new transfer function.
To get a good idea of what to do in what order and what parts actually do the best job, you can drop by our web site and look thru the performance packages, our various "Stage" kits - makes for excellent reading & guidance.
And of course, please feel free to give us a call for tuning or anything else performance-related, advice, etc., we'll be happy to help.
Best of luck!

In regards to the intake; you mentioned not to move the MAF so should I 'break' the intake before the MAF and put on one of my cone filters there? This way the MAF/meter and housing will be untouched and unmoved and no tuning should be needed for safe running?
What kind of power lays in the intake? Exhaust (high flow cats and muffs)? Tune?

Yes, you can use a MAF adapter and put a conical filter on the end of the MAF meter.
Briefly - a properly designed intake kit would yield about 15 HP at the flywheel - in terms of the gains form various exhaust mods, that depends on exactly *which* brand of product and how it's installed, etc., so for all your other questions, please give us a call & we'll be happy to help, OK?

Cool, thanks!
This is a 'beater' and I'm looking into the 'cheapo' solution to get over the hills for now... I have a tuning shop but they/we work on Mustangs and very little 2Vs now days... will have to look further into it as I want it to be worth while to spend the money... wish SCT let me use my one tuner for my two Fords...
