Piggyback Question

Hey guys,
I installed a Stillen S/C on my truck a few weeks ago. After installing the kit I put about 500 miles on it to allow the ecu to adjust, then I hooked up my wideband and scantool to it. The fuel trims are horrible and WOT AFR was around 14.5:1 (way too lean for forced induction). I'm also having some pinging issues (93 octane). With no way of retarding the timing and adjusting the map on the road I'm having to stay out of the throttle for now.

Anyway, I'll stop complaining and get to the point. Do any of yall know of a company that makes a good piggyback (like splitsecond) for the titan with self- tuning capabiliy? (Fuel mapping, open and closed loop, and timing retard) I've been looking for a while and I haven't really found anything.
I'd really like to toss the Chip that came with the S/C, install a good piggyback and retune it myself.

Don't get me wrong guys, I love forced induction and wouldn't have it anyother way. This will be the fourth vehicle that I've installed a supercharger on and once this one is done right I'm sure that I'll enjoy it as much as I have the others.

Thanks in advance,

Hey guys, thanks for your replies. I'll give Stillen a call and see if they can get me closer to where I want to be, or at least make it safer to drive. But the problem with a preset tune is that there is no way to come up with a map that works good for every truck. You have to factor in time of year (temperature) and elevation. With a stand alone unit and proper tools, you can create a map for summer, mild weather, and winter months. Then you know that you've have a perfect tune year around. Also, if any of you are like me and can't leave well enough alone, it would enable us to go to a smaller pulley without tearing anything up.

Stillen isn't the only company that comes with a non adjustable chip. Rouch, Kenne Bell and most other kits come this way. The differance is that there are cappable piggybacks available for most makes of cars and trucks for under $500, just not a Nissan Titan.

We need someone to come up with an online performance store just for the Titan, like Under Dog Racing Development does for Toyota trucks. Till then I'll check with the guys at split second and see if they can come up with an application for us. I've used them with Toyotas and there units have proven to be very reliable. (I've had one installed on my Tacoma for over 4 years now with no problems.)

Anyway, thanks again guys, and let me know if yall find out anything.
