    Spitting in boost

    Ok so i am kinda clueless on why it is spitting in boost. It only seems to do it when i am WOT though. So far i have replaced, spark plugs, fuel filter, sea foam, put injections cleaner through the system. Now all this start happening about a month ago or so. I started to notice after i ran the car up to 130mph.(stupid i know i was in a conflict with a v8 mustang and when i saw how fast i was going i stopped) But ya so i am clueless. It is currently running on chrome pro. So any ideas would be greatful.

                As for plugs i have them gapped at .032" i am going to lower them down to .028" this weekend and see if this does anything.
                I replaced the plug wires not even a year ago with ngk blues

                As for the ignitor i just replaced it but i know how easily they can give out i have a spare one i will swap and see if it changes at all

                        I am running an msd coil blaster. Did the conversion. But the coil blaster is new as well. I haven't replaced the coil wire that connects to the dizzy.

                            try gapping the plugs down to .025".

                            I assume you're in 5th gear at 130mph, under heavy load you may be leaning out, that could cause the spitting. Where are your A/F's and how much timing are you running?

                            I suspect that the plug gap is the culprit.
