have been running about 20psi of boost on me motor for a while now with no problems, but they wernt the best plugs or leads i woz used so thought i be safe and buy all new stuff for the ignition system, so went out and got me self a set of cossie motorsport plugs, beru leads, 2WD cap, rotor arm, and ignition coil all new, then gapped the plugs to 24 thou. but now car misses and splutters on full boost (never did this before) so ive turned the boost down and now its fine, but want to run the same boost again, any ideas as to why it does this at high boost and not at low, could the plugs be getting blown out? any suggestions would be much appriciated!

Sounds like a plug issue mate

 

May be overboosting mate

 

thats wot i woz thinking tiff, do you think they could be getting blown out or just not sparking properly, or gaps wrong? really would like to get this sorted as soon as.. thanks for the help.

 

na its got a unlimited boost superchip.

 

and it woz running exactly the same boost fine before i changed everything above.

 

hope u got the fuleing for 20psi sounds like ur spark is getting blown our on full boost that what i got on mine with the ngk plugs once. so i just put a set of 701s in and that cured the trouble

 

yea fuellings sweet, ive got a set of Ford Motorsport Platinum PP8 plugs i at the mo, you rekn the gaping could be wrong?

 

Viagra?

 

 

boost blowing the spark out, tried slightly bigger gaps?

 

if the boosts being blown out, do the gaps need to be larger or smaller? as i thought the smaller the gap, the less chance of it happening.
