  1. Another big Thanks to Dave at Cryotune. I got My tune in August and all of a sudden 3 weeks ago My DAM went to .75. I e-mailed Dave for advice and He basically walked Me through diagnosing a bad O2 sensor. He went out of His way to help Me out even though He had no obligation to. Thanks for the great customer service Dave.
  2. So I thought it might help some of the people considering getting a tune from Cryo if I described how i'ts gone so far. I got a base map first with instructions to log a 15-20 minute cruise before doing full throttle pulls. Dave advised the performance on this map would be low. It was but I noticed that He already had the A F learn #1 @ 3.99 or less and the fine knock learn never budged from zero. The full throttle pulls were not fast but smooth, the 2800 rpm stutter was already reduced, not bad for a base map. I sent the logs in and had a revision in a day or 2. This map did even more to smooth out the torque curve, almost no stutter @ 2800 and power to 6300 rpm. That was with boost limited to about 11-12 lbs. The next revision got the AF learn down a little lower and still kept boost conservative to maybe 13 psi. Still zero knock and just smooth power from the start of boost to red-line. The next map didn't really feel like a big change over the one it replaced but there may have been a little increase in boost, I think I might have hit 14 psi. The next map Dave sent was a different ballgame, the car really came alive around 3000 rpm and was very strong to redline. I was peaking at 15.25 psi with around 10 psi @ 3000 when the car really starts pulling hard. By now the AF learn # is down to 2.39 at full throttle and still not a hint of knock. The next map improved in what felt like another good jump. The car made boost in the high 16 to low 17 psi , the boost started around 2800 rpm and pulled real good to redline, I was at 90 mph in short order , there seemed to be torque the whole way. Just when I thought He had probably maxed My car out I loaded the latest map today. Holy crap, He turned Me up to 18 psi and it made a huge freaking difference. The car is totally an animal now. Dave wants Me to drive it for a week and then send some logs, it's gonna be an interesting week. I live in an area that is full of winding mountain roads with good pavement everywhere that put My JDM Rev. C suspension to the test now matched with ridiculously fun acceleration. The Cryotune ability is obviously high end and Dave is an asset to the forum. I can't even imagine what He could do in person but if I ever blow an engine , the new one will get a dyno-tune from Cryo.
  3. I posted this in the wrong thread so I'll put it here now. '08 OBXT, Grimmspeed DWG Dp, Perrin crank pulley and both silicone intake and throttle body hoses. Cobb AP running stage 2 LWG map. 98k miles and timing belts,plugs, etc. done 11k ago. Next up is valve clearances at 100k. At this mileage is a tune worthwhile and if so should I do the valves first?
  4. So I am considering getting a tune but I am looking for thoughts on 2 subjects. Car is '08 OBXT, Grimmspeed DWG DP, Cobb stage 2 LWG map, silicone intake and throttle body hoses and a lightweight pulley. At 99k miles is it too late in the engines life to get a tune? Should I check valve clearances first? All other maintenance is up to date @ around 11k since plugs,belts,water pump ETC.
