- 181 Lean solution
- 185 or Stacked Equivalent Lean solution
Great stuff.....lends cred to a "simple easily reversible upgrade setup...
65mm - 17psi - stock just makes it on AFR no retune necessary - within the capability of ECU
61.9/155 or 74/181 - ~18psi - upgrade to the 7.00228.51.0
and get a tune - ie: no need to change filter/reg.
65/181 or >19psi and you need to go with some 550cc injectors + fuel pump + tune but still keep your filter/reg. but your hitting 400-450 bhp and 300-350rwhp
HANG ON!!!!!
Apologies, if I have put any Walbro users off side.
good prices for a 7.00228.51.0 appreciated.
I found one in Aussie for AUD$375
here a little exxie for my taste tho.
