GSully23 But to answer your questions, before he swapped the tranny I did 3 25 mph rolls with him. Every time it was neck and neck, it he got me 2 out of 3 by a matter of a couple feet, I got him once. He wasnt willing to run at the track from a dead stop until he got his new ECM and toys. I also believe the shift flairs were from me changing tire sizes (I went to 35"s) and the granny didn't want to accept that. It might be due to my truck having the 3.31 diffs. All in all, I like both sets of tunes, I haven't switched back to the gearhead tunes because last time I tried it was 5įf and the tuner cut it short. I thought I bricked my truck but put 2 chargers on it, re loaded the tyrant tunes and all was well. I can say that without and aftermarket turbo/newer 15+ turbo the no limits stage 2 I take is overkill. I do plan to swap turbos here soon though and wont br looking back. No limit was great to work with, I dont regret there customer service one bit. But with my stock turbo only able to run 28 psi safely, if I upgrade to a newer 15+ turbo being able to run 35 psi would be great.

I can run my buddy's 240sx whenever he has the car running. Hes swapped a few trannys, hes always doing work on the car so have I ran him since than....no. I also have the stock 17" rims on with tires. I believe if I had the stock 20" s I would walk him. It's hard to tell without actually track data, i had a son and tore my acl riding motocross so i haven't really been worried about upgrading the truck. I'm healing up now and am looking to step up the turbo as well, so well see what happens than.

Captain1969 Running a Spartan tuner pull 40' 5th wheel and 30' enclosed race car trailer. 5 inch exhaust with muffler. The drone is terrible if you pull without a muffler around 65-70. Total delete. 161,000 miles tuner put on at 110,000 along with delete. Best friend had h&s just plugged EGR lost trans and turbo at 40k with his 2011 the other week. Tuner was only on for 10k he does beat the heck out of it but I'm not perfect either.

I have the GTX with Tyrant. So far there arenít any complaints that I can think of.

GSully23 The new "tyrant tunes" are good. Have I noticed much of a difference?...no to say the least. Personally speaking I can visually see higher low boost fueling, higher egt's, but much better low end.

With the GH tunes I noticed my turbo vanes cycling (I would see 1.5psi- -2.0psi, which I know I'm not producing vacuum) but regardless when I shut the truck off with the tyrant tunes i feel "I hear more stress put on the turbo/engine". It's hard to pick between either one, with the GH tunes I ran against my buddy's 240sx at a 25mph roll... he won 2 out of 3....which I haven't done yet with the tyrant tunes and i feel as if that wil be a sure fire way of telling the strong points of each tune.

boardboy330 Any update on the new tunes?

GSully23 Well yesterday I had finally heard back from No Limit, it took a few days and about 2 emails from me but that is completely understandable seeing as it's this time of year. I've never had any issues with customer service with them....and again after today I'll stand by that. Explained the dilemma I was having, I liked the gearhead tunes but I was wanting to buy the tyrant pack so I could compare and see if it sorts out a few of the small, and I mean VERY small things I've noticed with the Gearhead tunes (by the way, the GH tunes have done nothing but make my truck a much better truck altogether....sorted out alot of little issues like my 4th shift flair). I explained there wasn't an option to choose either one when I purchased, and I already had paid for SOTF with my other tunes. Jeff over there was AMAZING, he completely understood and offered me an unrealistic deal on the tyrant tune pack w/sotf....so I couldn't pass the offer up. I'm currently just waiting on the tyrant tunes and when I receive them I'll post a comparison. I have high hopes from reading what others are saying....but my Gearhead tunes are pretty good so the bars set pretty high IMHO
