So was I.
Out here on the west coast we have some of the best LSX tuners around. Any competent LSX tuner will tell you 3 dyno pulls is NOT ENOUGH to tune properly. If you try to tell me you can tune a TRex’ed LSX with no more than 3 pulls you are simply lying or pushing out very incomplete tunes. One of my good friends is one of the premier tuners out here and has done many TRex rigs. He can make them idle rock solid and have near stock driving manners yet put out amazing numbers (try 442RWHP in a stock LS1 longblock, yes 100% stock un-touched heads). There is no way he could do it in 3 pulls though. There’s more to tuning than just doing a few WOT pulls and dialing in the air/fuel ratio.
