200cc Injectors Causing A Flat Spot. Help.

[Greg205 0]

Just fitted some 200cc GRPA injectors to my 1.6, made an immediate improvement over standard, however at 4000rpm in 3rd when driving vigorously i hit a massive flat spot, any ideas how to sort this out? Do i need to upgrade my fuel pump, pressure regulator or get a new ecu?

(i'm running a custom airbox rated upto 400bhp so it's getting plenty of air)

 

Any help appreciated. Greg.

take them out, stick them back on ebay and fit your 1.6 injectors, problem solved

My 1.6 injectors were dead, anyway i've got a loyalty card at the petrol station!

get some working 1.6 ones then! simply chucking more fuel in will not give more power.
