Had some fun today with the TVS Cobalt. Just thought I'd share the results of some experimentation.

Mods:
ZZP Midlength Header, 3" DP with Cat.
3" Hahn Catback, no Resonator.
Some 2.75" CAI.
Siemens 60lbs Injectors, using correct IFR table (1.3x multiplier to stoich)
Dual-Pass, Option B, ZZP S3 Heat Exchanger.
BKR7E Coppers Gapped 0.030"
TVS-1320 with 3.15" Pulley.
FE5 suspension and some Shitty TTR motor mounts
STOCK clutch (Yes it slips on shifts, causes KR because of the Vibs occasionally)

Fuel: 50% 91 octane Gasoline, 50% E85 summer blend
Timing: 25 - 27.5 deg advance during WOT
Fuel Cutoff: 7250rpm
IDC: 101% @7200rpm
MAF Freq: 10,300 @7200rpm
Boost: 20psi @7200rpm
Dynamic: 3600rpm Disable



Owner is putting 80s, Fuel pump, BRFPS, and going FULL E85 very soon, then time to experiment with smaller pulleys.

Thing pulls like a beast

 

tune looks good! a fuel pump upgrade and RSFS will net you a bit more when you up the FP.
