So I bought my tune back in December and between the weather and just being a wuss, I finally got around to installing the tune today. I did not previously own a laptop, so I found a free Sony Vaio from circa 2002 and installed Windows XP Pro with all updates (high priority and optional including .Net). It has a Pentium III processor with a 15GB HDD, and 128MB of RAM . . . but previously I read that if it can run XP than it can run EZ Flash no problem.
Well in the end it installed the tune with no issues, even on that ancient hardware, but it definitely reinforced the need get a more modern machine. This dinosaur took about 1 minute per 1% of the tuning operation, so all told with the transparency mode enabled it took about 2 hours to install the tune total. I didn't really expect this, so I had sat in the driver's seat with the door shut (with an extension cord running to the laptop out the passengers side back to the house) and was afraid to move/open the door/etc. for 2 hours. I thought my bladder was going to explode!!! So lesson learned, use a computer with decent, modern specs. So yeah if anyone has a spare, cheap laptop laying around that they want to donate to the "Chad doesn't want to sit in his car for 2 hours while tuning fund" let me know!
Now to the fun part. After installing the tune and enabling transparency mode, I cleared the TCM adaptives and decided to take her for a short spin. All I can say is WOW. I started her off in Sport Mode (I've got an automatic) and the car finally drives like I hoped it would after installing my Vararam CAI and Vmax ported throttle body. I asked for firmer shifts and in Sport Mode it feels really aggressive, but not to the point of being annoying. I did another couple of miles in Drive just for comparisons sake, and Drive now feels like Sport Mode used to so I may actually use Drive now! (I previously drove it exclusively in Sport Mode). So now I'm going to drive it around for the week and shoot for some datalogs next weekend.
I would just like to state that my experience with trifecta was exellent. I have a 08 cobalt ss turbo black in color. My mods are: Hahns cool ram intake Hahns charge piping Hahns Inter cooler Hahns Cat con downpipe Hahns Street cat back exhaust Clutchmasters stage 3 with aluminium flywheel Gms1 I got the select a tune which i chose to get on my cruise control button, best option to have lol I wondered how much more power i would get over gms1. Well now at 40 km-hr at 2000rmp the tire light up and i mean light up. When the boost reaches 23 psi wow!!! the car is so much stronger throughout every gear. The gms1 tune looses alot of power pass 5000rpm the trifecta tune keeps pulling!!! Very happy customer!! My ultimate goal is the s20g turbo upgrade now that i have seen that my car can handle 24psi spikes and hold 23 psi, my clutch and transmission can hold that much torque. It is time to get it!! No issue to engine light no codes after tune!!!
Very Impressed with the new performance! The engine is much more responsive than stock, particularly in 5th or 6th gears. When in stock mode, and 5th or 6th (manual trans) you had to be aware of your speed and of the terrain, or you had NO power. Now the little engine pulls willingly above 2000rpm. Second gear is FUN, and will take you past 55mph in a hurry. Third gear pulls almost as well as 2nd, above 3000rpm. Excellent throttle response, excellent acceleration in all gears, at all rpm, and at all throttle positions. The Trifecta tune for the 1.4L Cruze was well thought out and well executed. Thank you for turning my little econobox into a FUN machine to drive! Tom
Made worlds of difference in our 2007 Solstice GXP 5 sp. Stock the car is rated 260HP/260Trq at the crank. After your budget tune I paid to have a 3 run Dyno here in our area. At the wheels, 280.97 HP/321Trq. Nuff said! WOW!!!!!!!!
