Hi Guys,
So here is my story: I installed my FRPP 4.10 gears about 3 weeks ago after 1-2 days of installing it the car lost alot of power it feels that im driving a stock mustang !!!!
Car specs :
-05 Mustang Gt has around 93,000 miles on (150K Km)
-FR cold air intake
-SLP muffler delete
-4.10 FRPP Gears
- DS custom tune
- 305/45/18 drag radials
What I've done right after the Gear installation
- Changed the axle ratio on the tuner from a 3.55 to 4.10 (Didn't add or change any premeters except for the axle ratio, the fuel to air ratio is the same )
- Cleaned TB
Please dont tell me your tires are too big,
i ran the same tires on the 3.55 and frankly speaking i don't see or feel much difference with 4.10
Is it possible that my engine is loosing its compression ??
or do i need to retune ?? or what ???
One more thing anyone has access to a DS tuner in case i need to retune ??
Thank you in advance guys
