ok guys i have a 99 L that i want to know what would be the sest tunes for. here are my mods: 4 lb lower 2.8 upper apten ported blower jlp ram air 90mm mass air 170* (tr6 or ? havent decided yet) oil seperator ftvb and will have a wideband a/f if Sal ever email's me back. the chip i have is a diablo revolution flip chip (stock and 2 programs) the only downfall is that i can only get 90-92 octane here. what are some ideas on what programs i shouod ask for to be burned on my chip? thanks guys

 

without a dyno you have to choose& trust your tuner!! for that crappy gas, you have my sympathy. Good luck

 

i thought about using a mild tune for one program and a more agresive tune for the other, just incase i get the opportunity to run a fast car on the street, wouldn't even know where to get 100 octane around here. on the diablo flip chip there is the stock setting, could this be modified as well? i have added a 90mm maf and an apten w/pulley's, but would this be safe to ever run the stock setting as long as my a/f ratio's are good?
