Question about fast intake, fuel injectors, and tune. So i purchased heads/intake/ new 36lb fuel injectors. I am waiting to do the heads till I can afford a dyno tune and testing. I was going to do the new fast 90 on my own. Is there any harm as far as upgrading my fuel injectors now or should i wait till i can tune it for the new injectors? Also does TSP sell the fast with all the bolts and seals i need for the intake? BTW car is an M6 01 ss. mild cam and exhaust making 376rwhp.

you can install the new intake manifold without a tune, but the injectors will have to wait. Honestly, if you have the intake and the time to install it now, it won't hurt and the injectors are easy to swap out later.

When I bought my Fast 92, it came with new bolts. However, Fast also makes a port seal kit which I purchased seperately. As noted above, it isn't too difficult to pop the injector rails and change the injectors at a later time.

It isn't too hard to change out the manifold with the injectors either. I would not aggressively drive a car that had a change that increased air flow. In a perfect world the MAF should adjust for that but they usually don't and need retuning. As such I'd do everything at once.
