At this time I think I am going to find an ecu that is "chipped" for mods like these since it is only bolt ons. Blitz, mines, etc made a bunch with different fuel maps to accommodate bolt on mods. I'll see if I can get my hands on one.

Also looking at a FPR gauge that has a sender to inside the vehicle, and a wideband.

Some of those ECU's are not tuned on the car with a dyno. They are generic tunes (one tune for many cars, just like factory tune) and meant to be used with parts from the tuners that make the tunes (parts have to be the same). If parts are of a different brand they flow differently, etc, which can affect ECU tune.

If on a budget, keep stock tune and fit higher lph fuel pump, hardwire kit for fuel pump, adjustable Nismo, Sard or similar FPR to adjust fuel pressure to suit (or slightly richer). That would prevent engine running lean with the mods (closer to factory A/F ratio's) until you can buy Nistune, etc.

So literally just upping the fuel pressure would counter this on stock fuel maps?

**EDIT**

Most likely going to just go with nistune, trying to discuss the cheapest way of getting it as funds are tight.

Thanks for feedback guys
