Today i made the trip to Z1 Motorsports to get dyno tuned using Osiris. Last time i dynoed,i made 257RWHP and 238LB/FT. Well, since i have changed rear tires to heavier 285 Run Flat. So today i baselined at 253HP. We found out that i was running EXTREMELY lean, just by adjusting the A/F i was over 260RWHP. Jon spent about 4hours tuning and i ended up making 265RWHP and 250LB/FT on their DynoJet. I also gained 17HP and 16TQ in the midrange. I feel like this tune is the most noticable thing ive ever done, the car pulls ALOT harder and is smoother than ever before.

I have a 04 G35C 6MT
My engine mods include:
JWT Popcharger
Stillen Z-Tube
AAM Angled Plenum Spacer
NGK Plugs
JWT Lightweight Flywheel
JWT Clutch
Stillen Test Pipes
APS True Dual Exhaust
Stillen Underdrive Crank Pulley
and Amsoil Fluids

I would like to thank Z1 and Jon for providing such a great tune.

Here is my chart, and i hope to have another chart soon, as i plan to install Longtube Headers, upgrade to a Kinetix Plenum and retune.

 

nice gains man. have fun

 

thats pretty solid. I need to start looking into doing some stuff.
