this is my first build, 88 gt, and my car seams to be hesitating off the launch, last run was 8.86 in 1/8, still have the 19lbs but I think I need more...302 stock bottom crank and pistons, my mods are TF twisted wedge aluminum heads, TF push rods, ford racing rockers, TF stage 1 cam (4.90 or 5 lift I think), TF track heat upper & lower intake, TF 1" spacer, dbl roller timing, 70mm bbk tb, bbk cold air intake, maf installed, computer from 93 cobra, aod with prof product shift kit, 2800 stall conv with cooler, 3.73 rear end...Im planning on adding a 150 shot and maybe a 4.10 gear if the injectors don't help....im just unsure if I should get 30lb and back the pressure off or run 24's wide open? thanks for any help or advice on anything...

I'm not sure if the injectors are the problem here. Has the Fuel pump been upgraded? One way to troubleshoot is to have a fuel pressure gauge visible when launching to see what the pressure is doing and how much it may be dropping. I have have seen plenty of cars running your combo with 19lb injectors and run fine if you do determine it is the injectors the 24lb will be more than sufficient for your application.

Have an 88 with a 93 Cobra motor. Edelbrock performer intake gt40heads f303 cam.... Cars very quick haven't had a chance to take it to the track yet. Only have 19lb injectors In it right now but wondering if upgraded to 30lb or 24lb would give it more power

19lb injectors will support up to roughly 270hp at the crank. Past that, they are maxed out. 30lb injectors will be too much for that combo. 24lb are what most run and they are not going to give you more power, they will simply allow it if that makes sense as they wont be maxed out. If you swap to 24s, be sure to get the matching maf.
