what is the SAFEST degree to set timing at when filling up with 91 octance in a 99 GT. i cancelled my disblo predator order and im just gonna go get a custom tune... so i want to know what degree to set the timing at once i get the chip burned... im thinking 13 since 14 is MAX ... but maybe 12... i dont know ... u guys tell me... also i live in california if that makes a diff

 

14 degrees advanced. You may try 15 and see if you get any surging or CE light. If not then keep it there.

 

14 - 15* initial usually

 

so 14 it is lol. thanks guys.... ok here is the thing.. i didnt cancel the order yet... but i will on monday so i can just save that 350 for a custom tune... around how much does a custom tune cost first of all? and second of all , i know if worst comes to worst and i have a chip burnt already without the rear end gears yet... i can get a speedcal to fix that... but do speedcals also fix the speedometer if u get bigger wheels and tires?

 

chips can be re-burnt too. so can programmers, they can be programmed to do any tune. Look into the new SCT if you havent already, those can be re-burned via email.

 

Hey Joe... that chip I have is from JMS? I cant remember. LOL If I need it reburned I wold have to take it out and send it to them, right? That would suck. LOL

 

the predator can be reprogammed via email, for 100 dollars you can get a custom tune and get it changed anytime you want to after that for free, it you bolt ons just let them know.

 

so would it be a better value to just get the predator, get a dyno test , get the right numbers. send the dyno numbers to diablo and have them make a tune with the dyno results i get , and then send it to me ... OR would it be better to just not getting the predator, getting a dyno numbers a custom tune and that tune burnt on to a chip all at one time at one place...?

 

Best thing to do is, install the mods you want to do, wait until your finished, then get yourself a dyno tune.

 

hey dan02.... how much do u think it would cost for a dyno tune and a custom chip?... juts so i know about how much ill have to save
