Intake and tune that is in the 1/4 mile and zero to sixty times? Who's tune are you using?

 

Are you trying to just isolate the benefit of the tune itself? If you are, I have no idea because mine, like most, was coupled with a CAI and its hard to say. But after my CAI and tune from Bama, my times dropped by a solid 3 tenths with similar weather conditions first run out.

 

As mentioned above, most of us combined a tune/tuner with another modification which required the tuner in the first place.

That said, the very first mod I did to my 07 GT automatic coupe was 4.10 gears and a DiabloSport tuner with their canned tunes. I never ran the car bone stock, but it should have run 13.80's or 13.90's @ 99-100 mph in the 1/4 mile per most road tests. With the 4.10's and canned tune, I went a best of 13.36 @ 102+. I'd venture to guess that the tune was responsible for all of the mph improvement, while the ET improvement was likely 50% from the tune and 50% from the gears, IMO.

A decent premium fuel tune all by itself is good for 20-25 rwhp in the 2005+ GT's.

 

My GT/5-spd went from 279rwhp/293rwtq to 282 rwhp/300rwtq with a dyno tune. Picked up some good avg hp across the band.

Mods were K&N CAI, FR500S mufflers and ran on 91 octane for a tank or two before the tune.

I used the canned tune and then adjusted the fuel trim and timing on the dyno. Nice flat A/F curve.

 

picked up just over .3 in the 1/8th with my tillman tune.

 

I edited the first post. Yes I was wondering what the tune and intake did for you from stock to intake and tune? Thanks

 

my results were with a jlt also

 

My car with a mac axle back and pypes off road xpipe went 13.3@104....got an xcal 3 with vmp mailorder tune and it went 12.97@107 still with the original paper filter, now the 3.31's are gone so i'm anxious for nice weather!

 

you went 13.3? on those two mods? and 12.97 with the addition of a mail order tune? No other mods? i would say that is pretty darn good for a basic setup.

i never ran my car before i got to get out there and practice and see what my car is capable of.

 

Yes sir, down to the original paper filter (48k miles now )...I will add that was on drag radials and 60' on the 13.3 was 2.0 and 1.9 on the 12.9 pass.

recently went with 4.10's now so the goal is going to be 12.599 when cool weather gets near.

 

Alright, that makes sense now that we know you were on drag radials.

 

yeah, odd part is that the car cut roughly the same 60's on street tires...explain that?

 

I know my car was running a 14.2, (mainly my fault but even with an experienced driver it still would not break 14.0) but after adding the JLT, Steeda Econo plates, offroad h-pipe and coffin mufflers with Tillmans tune the car is now running a 13.7 with the stock tires and 3.31 gears.

 

Tuner made a big difference. On the strip going from stock to a C&L Street & Diablo tuner with the stock tunes that came with it I dropped 2.5 tenths and gained 3MPH in very similar weather (mid July). I then switched to a SCT2 with Brenspeed tunes and no other performance parts aside from the above C&L Street intake and with a 91 Octane tune I dropped tenth and a bit and 2 more MPH! My more aggressive 93 octane tune with much firmer shift points dropped down another half a tenth and had a negligable gain in MPH.

So from beginning to end with the only variance being weather and the type of tuner I used I dropped 5 tenths and gained 4MPH. I am sure the motor loosening up probably helped a bit in there as it got more broken in.

I haven't been back to the track since I added my UDP and gears, I'd love to see those 12 second slips (corrected) I was close to getting. Now that I live at sea level I just need to get over to a track and find out!

 

First run with my car, bone stock with 5-speed manual, 3.31s, and 18" Bullits, was 13.69@104.10mph. Perfect weather conditions I guess. Ran a bunch of 13.70s and 13.80s after that at 103.xx.

With a Bama 93 Torque Tune and a JLT-II filter I ran a 13.43 @ 105.13mph, spinning really bad going into 2nd gear. With a better prepped track, that would have been a 13.30@106mph run easily.
