Would it be beneficial to upgrade injectors (currently 24lb) and a better MAF.

AU2 XR8 5.0L with GT40X heads, 224/218 Cam, 2.5"twin system, ported explorer, stainless inlet pipe, auto, and CPU flasher

cheers

Injectors should be OK (was it originally a 200 or a 220?)

MAF will be pretty close, if not maxed out.

it was the 220kw version.

what do you mean maxed out

i have heard you can knock out that centre spine in the MAF to get rid of the restriction...is this worthwhile?

i was gonna do this also but apparently it throws it all out of kilter... and the whole thing has to be recalibrated

another cheap mod foiled :(

A 70mm maf is fine for your setup. If its running out of fuel with your current setup spend the money on a flash tuner

x2 for sticking with the current MAF.

Even if it is maxing out, i dont expect it would be enough power to affect the tune too badly.

have heard of someone on here running a t-series MAF body with the 70mm wires in it ....would this totally stuff up the MAFtables and cost you a fortune in dyno time to get right ??
