GN made 2 loud pops

[TurboVic]

hey gang.... been a while and now a newbie again. I have a GN with 16.5k miles on it with some tasteful mods and from a stop I got on it today and heard 2 loud pops under the car. It has razors alky and the fuel system was all upgraded with 60lb injectors. doesn't seem like torque converter or trans....maybe electrical or fuel? has drag radials so no much wheel spin.. any input please would help... thanks
PS about 18lbs boost 0 knock..

has all upgraded exhaust and down pipe... seems all tight and fittings are good.. Still ran and shifted fine after that....car is real strong,,,,thx

Coolant in oil?
Oil in coolant?
Smoke from exhaust?
Is battery voltage good?
How loud was the pops?
How much boost when it popped?
All vacuume lines still where they should be??
Did you run out of alky?
How's your fuel pressure?
Intercooler hoses tight?
Any exhaust leaks?
How were your 02 readings?
Should I keep asking questions?
What have you checked?
If you get on it, can you replicate it?
What's for breakfast?

Coolant and oil good...
no smoke.....
battery voltage good...had a loose cable today....tighten it earlier..
pops were pretty loud,....that's why im concerned...
not much boost...was just coming off the line. I may try turning down alky...only on like 2..
went thru vacuum lines recently.....ill check again...
fuel pressure good....
intercooler up pipe hoses good...all new silcon with good new t clamps....
no sure about exhashst leaks.....bolt on kit seems good and tight...
02 good...
going thru everything obvious I can see so far....nothing jumping out...
drove great after that....strong....shifted well ect....
I have torched a converted before and had other issues with my previous 600 hp GN...
doesn't seem same...like backfire but louder....
had eggs on a bagel.... thx

ILL check the motor mounts and get more into it when she cools down....I know these drag radial tires are harder on the drive train.... car has only been driven about 400 miles in last 3 years before I purchased....been a pleasure and is very strong for a stock engine with some mods... first time this has happed with it .....ive had it about 4 months and put just over 500 miles on it ....get it out once every few weeks

All Scan Master numbers look spot on.....tuned car to 18 - 19 lbs of boost with 0 knock always.... TA 49 turbo and upgraded stock location intercooler also on car....Turbo tweak chip.....Stock Air intake with K+N.....I know I know....im trying to keep it stock appearing... car is amazing,,,took me a year to find....Interior is perfect....beautiful factory paint...I did new fuel and oil filters...additives...flushed coolant and added distilled with royal purple ice....all body braces...ceramic clear tint to protect from UV rays.....slowly going thru everything on this car.....Super Happy!!
