TTA-Injectors & chip
Jack,
I purchased an 89 TTA about 10 years ago with many ATR mods. The car has a stock block and heads. I am currently installing forged pistons and noticed it has a double roller timing chain, so I think the cam has been changed. I do not know the lift and duration of the current cam. I also had the manifolds, crossover and down pipe high temp coated. Here is a list of what I do know: ATR SS 3" down pipe; test pipe and exhaust; external waist gate; Adj fuel regulator; Stage 3A turbo (TA-49?) ; ATR SS inlet pipe; 5207009 injectors; Prompaq which holds 5 chips. The car came with the ATR pit bull, ATR strip chip and stock chip installed in the chip changer. I added a Duttweiler chip. I think the car needs larger injectors and a chip to match. Was the ATR stage 3A turbo a TA-49? Do you have any recommendations for injectors, chip and changes while the engine is still unassembled?
Thanks for your knowledge
