so i need a tatrix cable and a lab top

 

Ding ding.

Or I dont know much about the cobb access port. I believe you can have 2 or so maps on there without a laptop or tactrix but its expensive

 

how much is the cable???

dam it's cheap, so now let me get this straight with that cable and labtop i could have sean ivey tune 2 maps one for pump gas and one for race gas.

 

yes

 

Don't forget to download ECU Flash and Mitsulogger or EvoScan

 

thanks fellas

 

Let me know how it goes, because I'm thinking of getting a race gas flash as well

 

if you run straight or almost straight racegas and especially more than 105-108 octane the car probably will run slower... mine did!

now if you tune on a specific racegas then the car will be faster...

If you use a racegas mix just to bring the octane level 2-3 numbers more then you run run a bit more boost and make more power...

 

I saw this in person...

A co-worker had a SRT4 with a 2.6 stroker motor and 60-1 turbo. At 22 psi on 91pump gas (partially tuned, running low timing) he made 442 whp. After adding 100 octane, no more boost and no adjustments to the tune, he made 484 whp. But it does burn slowly and it is definately best to have a map that you can swap into your ECU for race gas due to the fact that it does burn slower.

 

well i should note that my "test" was made with leaded Sunoco 116 octane... Maybe if i had used 100-103 unleaded the car would respond better...

 

you can go up quiet a bit just with timing alone @ the same boost.

 

tune it first....

 

you might as well just get dedicated pump octane and race gas maps since it's so easy to flash between the two. i never did trust putting a few gallons of race gas in and turning up the boost. you'll either be leaving HP on the table or running lean.
