I currently have a dual nozzle progressive alky system with two M10 nozzles and it works great. My car runs 10's on 93 and alky with zero knock retard. I recently upgraded the turbo which of course means more air flow so I added fuel thru the TT chip to compensate. I was/am thinking that I might go to two M12 nozzles to make up for some of the fuel then add any remaining needed fuel thru the chip then once I get it tuned send the chip back to Eric and get the default fuel changed to value that the car liked. In its current condition more meth isn't needed but are there any downsides to running more? My tune is pretty conserative and there is plenty of boost left to go and I haven't added any timing so far so there is some performance left on the table so having more meth seems like a good idea so I wanted to see if anyone has tried it. Thanks
