spark plug gap on paxton ? down on power

[beata]

didn't get a chance to re-dyno the car but pulled plugs out to find they were gapped @40 instead of 30-32.would this have caused a wavy dyno graph in the 5000 to 6000 rpm also down in power (60-80hp)..thx

nobody have an opinion?

I run my plugs at around .030 on my Paxton, which makes about 16 psi. I also run plugs that are probably 2 steps colder than stock and use cut back straps to expose the spark better. I believe they are Autolite AR3933's. Never had a problem with them. I only change them out every year or two just because I believe it's good maintenance. Never had a spark/ignition related problem with them.

You could also be having some belt slip issues. That will also result in a "wavy" dyno graph. Try to log the boost next time and see if it's wavering up and down at the higher rpms.

no leaks on boost checked to see.. also have the dlm tensioner. supposedly have a proven tune..

was the "proven tune" done in person or is a canned tune ? big difference....

was done with remote tuning..eliminating the Split Second and tuning with SCT...
