Does this car have a over heating problem? because your overheating protection is higher than normal. You stated 880cc injectors but in the calibrations it say 480cc injectors. How much HP did it make on the dyno?

it made 430whp on 20psi

Its never overheated and runs pretty cool, and i saw the 480cc part and was trying to figure that out...

If you have 880cc injectors installed, you should ask your tuner why he has 480cc instead. Orginially the overheating protection was set at 220 deg F, your car rev limiter is 8223 rpm but your protection limiter is 10026 rpm, so it wouldn't be effective. After looking at both low & high ignition tables I think you should get the car retuned. If you look at 5000 rpm row in your low ignition and then at it in the high ignition you will notice the timing is down a whole lot in that area:shock:

Was just wondering why the fan over ride was checked to come on at 100 degrees. Also, with the previous statements about the injectors, I would verify the offset for them as well when you get it retuned. You should be able to contact the manufacturer of the injectors to get some or all the numbers you need for that. Timing looks pretty extreme towards the top at 12 to 27 pounds. I believe it was 21 down to 5.50. Your cold cut and hot cut are set to the same 30 pounds which if you are only a 2.5 bar your chances are you will not see that.
