· Retuned air/fuel ratios reduce the amount of engine knock and knock retard;
· Transmission shift points that have been remapped throughout the entire throttle range. The transmission will upshift in a sportier manner, downshifts are more responsive to throttle input, bogging from torque converter lockup greatly reduced. Skip shifts are enabled, to allow the transmission to shift down to 1st gear up to 43mph (in cars with performance shift mode), and to 2nd gear on the highway up to 85mph, giving more power available when you want it.
· 2nd gear start added to provide better traction during winter driving. Manually shift into 2nd gear starts in 2nd gear.
· Performance shift mode added - changes engine characteristics on how the transmission shifts and rev limiter changes etc..
· Transmission fluid pressure controls are completely remapped to provide consistent shift quality and reduced shift times for increased performance and potential increase in life expectancy of electronics and hard parts from reduced slippage of clutches, reduced fluctuation of fluid pressures based on small changes in temperature and engine output, and revised torque management allowing reduced engine power during upshifting and downshifting so the transmission doesn't have to change gears against the full power output of the engine.
· Proprietary use of boost control at part throttle limits boost spikes and boost early onset. This reduces the need to activate performance fueling too early and reduces burst fuel requirements.
· Deceleration Fuel Cutoff and Deceleration Enleanment has been reprogrammed to be more aggressive, saving fuel when decelerating.
· Idle speed is slightly increased to smooth idle vibrations from polyurethane motor mount installations, to increase cooling and charging at idle and power steering assist at low speed turns.
· Air/Fuel ratios in abuse modes, rev limiter and traction control modes are reprogrammed from dangerously lean to more acceptable levels incase they activate during performance use. -The timing advance dip that occurs during the transition from cruise into boost is removed for better mid-throttle acceleration.
Engine:
· 180deg thermostat
· Full fender well intake
· 75mm Northstar throttlebody
· 3.4" supercharger pulley. Increases boost from 8 to 11psi.
· Flowmaster mufflers
· Removed "U" bend to reduce exhaust restrictions
Thats what was in the ad when the guy sold it to me. i havent done an "Engine" mod since, ive added a new grille and LED Tails, planning on projectors in the spring when this damn snow clears up and then puttin my 18" American Racing rims on that i had on my Grand Am.
ive had the car 2 months or so and spring is coming..
Need to know what are my next best options.
Headers are an obvious one, then what...
Posting where to get em, what parts il need, HP gain and install hours would be greatly appreciated.
My bro wanted to know how much a cam would do for this car ( a GTP) horsepower wise.
PS. He has a 98 Mustang GT 4.6L V8 (Automatic). He plans on doing a swap for most of the parts from a 99-04 Mustang and adding 4.10 gears etc.
How close would we be in a race?
