detonation vs ignition miss

[bretthejet26]

just wondering something... i had my boost from my mbc set at 14 psi.. now on occasions i will go wot and get my car going... at 14psi it will miss and stutter this happens about 75% of the time. so i figured that was bad so i lowered the boost to about 10psi and i go wot.. and it doesnt miss at all.. so im wondering if its detonation or just a miss... or is there a difference between the two. i also notice that the misses seem to happen on more warmer days rather than very cool nights where i pick up a lot of boost.. thanks in advance

Hvae you done a boost leak check. Sound like some of the clamps are not tight and at higher boost you are having a more nitcieable leak.

Dont quote me on this but when my previous car was missing under wot I replaced the spark plug wires and that got rid of my problem. If you have a shop manual take your spark plugs off and check them with an meter. Hopefully that helps
