I purchased an XCal II about a year ago from TP for my 02 4.6L Screw. I have since installed a 2003 Lightning motor. I was wondering if I should have TP send me an updated tune, or should I go to a local tuner who can dyno tune the setup? My Local Tuner being Patrick at PSI Motorsports in Houston.

 

I was very happy with my Troyer tune but I've only heard good things about PSI and Patrick's work. He has tuned some very fast trucks for HALO.
If I still lived in Houston, I would probably go there.

 

I feel the same way about both. I wonder if the XCal is locked by Troyer Performance? I just know how to load the tunes into the PCM, but I don't know how to create new tunes. I guess any tuner could program some new tunes into my XCal, correct?

 

when i got rid of my troyer tunes i went to vmp tuning. i was able to erase my xcal2 with software from sctflash website. it was easy. being as you are supercharged i would say yes an inhouse dyno tune is going to be better as they will have the truck right there.

 

I'd do the dyno tune first. If you want a mail order tune, give VMP Tuning a shot they do great work and have great customer service. The owner used to work for SCT, too. Troyer is pretty good too.

 

try i ride suzuki's custom tunes

 

Stop cross posting, it's getting childish. Keep that stuff in that thread and try to answer some questions instead of trying to ruin people's threads. Thanks.

 

A dyno tune is the best hands down. That is if you can get someone in your area that has some experience.

 

and is familiar with the F-150 platform and its multiple strategies

 

mike nailed my mail order tune with the 4lb lower. when i went to a dyno day at his shop just took one pull and found a/f was dead on. i love mikes tunes but if i was that close to psi and hearing all the good about his shop, id let psi tune it.
