I installed some RC 750cc injectors the other day and installed a new basemap chip in my p28 on my built turbo gsr setup. The motor fires right up, but after about 30 seconds it starts fluttering around 1000rpm....everything is upgraded besides the FPR. I couldn't find any vacum leaks..

I need to get this fixed so i can drive it to be tuned...

 

get a different basemap.

have you always run the p28 or was that an addition too.

platinum.

 

what are you using to check the fuel?... you need a wideband, dyno.... or good LUCK to you....
they dont idle with a map just with injectors sizes changed..

 

throw in the old injectors, drive it to get tuned and throw the new ones in when you get there...

 

It has always had the p28 ecu. I wish i could throw the 370's back in and drive to the dyno but i sold them already. I 'm just going to trailer the car to the dyno and stop messing around with basemaps hoping to find one that idles correctly.

 

i might be able to hook you up with my 750 map... it idles nicely at 700... i did it myself with a wideband...
are you using crome or uberdata?
