Hi lads, heres my delema, have 00 sti 4dr, with following mods straight through exhaust, ninja back box, green panel filter, walbro pump, ngk7rb plugs and andy f remap for 95oct and mods 1.25 bar boost. i am in ireland so 95 is only fuel available, i didnt not want to use octane booster so got it mapped for 95 only, there was good difference in car when andy done his thing with it, but now like every one i want more power, only thig i dont know what to do next, the feeling that im getting from people is that there is a cap on my power once im using 95 and that i cant get much more with booster, is this the case???? or is there a path to take???? i have another post up bout water i injection, if i got this would it be the same as adding booster, could i map for more boost advance with wi, does booster do more than just bvring down temps, appreciate your tips guys

 

bigger turbo, larger injectors and a front mount?

 

thanks for reply but thats where my problem lies, i asked andy f bout bigger turbo and he said that he never mapped one with 95oct so he wouldnt be sure of results, so dnt know if it would be safe or if power gain would be good

 

As briforbes said really, but if your unsure of the turbo, why not go for a Bigger top mount intercooler, this should bring the most out of your standard Turbo.

Also Andy said he wasnt sure..........thats not a no, but it could mean trial and error which could be costly.
