possibly leaning???

[da40]

well i recently upped the boost on my sr set up to 17psi from 15psi..my set up is a s15 bb turbo(real deal) redtop SR,walboro fuel pump,550cc inj,ethalpy ecu,z32 maf,i have fmic,all the piping from the turbo to the back is 3inch or bigger (j pipe,dp,catback) upgraded clutch aswell,welded diff too..thats mostly it besides the other usual nessities anyways the car kinda seam a little slugish when i really get on it like almost as its leaning alittle up top the first 2 gears seam ok but my 3rd and upseam odd to me i know at 15psi i was running rich (back firing all the time sometimes flames pop out the exh..cool!) so u guys think i can be leaning out even with the ethalpy and the injectors i welcome everyones 2 cents thanks in advance guys....

17 psi is going to wear that turbo out fast.

Also your running more boost on a tuned setup? A tune for 15 psi will lean out on higher boost.

well its not actually tuned on a certin psi, its an enthaply ecu ,and the gt28r suppose to be good for atleast 18psi from what i hear

im thinking i might need a safc or something

email chris at enthalpy and ask him. he will know best about this. imo i dont think upping the boost on an enthalpy tune will lean you out. the maf is supposed to pick up the extra air and compensate by adding more fuel when more air is present. just my 2 cents
