[JoEgsX90]

Ok guys i have a gst 2g with a 6bolt block built by machine shop bored .20 over....and i have a 2g head on it with 5 angle valve job and 272 BC cams. 16g on it with a big front mount intercooler hks recirculated bov. Dealing with a boost leak right now so im only running 11 psi. also has a 190 rewired fuel pump..All other mods i forgot on my profile. I was wondering what do you guys is the next think to put on it.... I know dsm link is good but honest cant afford it and ecu not eprom... I was thinking just going with safc 2 used about 150 is it worth it?? also have stock injectors and NO wideband. Let me know what you think

if you want to mess with fuel,you deff need Wideband and logger,then i would get an AFC,Because tuning your afr without any logging device,would kill your engine soon.... Lets say if you buy an afc fIRST,And will tune your car to a lean side,the motor will blow by detonation

whats the least expensive way to go with the logger wideband?? or can i just get the regular A/F gauge.?

Dont even mess with A/F gauge its a waste of money and wont do anything for you. Theres alot of wideband sales going on right now id look into one.
