If so, I would recommend spending the money on:
$300 intake valve cleaning
$240 coils & spark plugs
$400 5" FMIC
$180 chargpipe

Then run MHD stage 2+. This would require an Android device and a DCAN cable, both can be had for ~$100. You would then need the MHD license + map, which would be another $150 I believe. So total MHD tune=$250.

This totals to $1370. Add BMS dual cone intakes for $95 and you're at your budget. From there, set aside some money for when things go wrong. Water pump replacement is $450, and that's if you're doing the work yourself!
The car has just over 80k miles on it and will be checking the intake valves when I get the time to see if they need to be walnut blasted. Will have more money to spend on the car in the next month also, the goal is to get this car to 450hp and keep it as reliable as possible. I don't all my work and maintenance myself so i don't have to worry about any labor costs
